Future Thinking

1. Description

The name of our product is iTransformer.

The concept of iTransformer is for easier carrying, multiple usages, and human touch. By 2025, most people will choose this technology, since it is a choice to reduce losing of mobile phones, a choice to have 4D talking with contacts, a choice to have a ‘soft’ technology in daily life.

This technology, or to say, this kind of mobile phones with the specific technology allows users to ‘wear’ it in many situations. There could be many models for users to choose. A watch phone is no longer a novelty in 2025, but a watch phone with 4D technology build in could be a new trend for iTransformer lovers to follow. A phone that can bend and fold will increase a lot fun to users while they using their phones.

Based on past experiences, most people will feel tired in the shape or appearance of their mobile phones. Plate rolls users may want to have a clamshell phone or a slide phone. With iTransformer technology, people do not have to buy a lot of phones in order to fit in the fashion trend of mobile phones, they can buy only one chip, which looks like a SIM card in 2010, it is not only a user’s information and contact list chip, but also an iTransformer technology installer. With this chip, users can transform any kind of mobile phones into the shapes they want, which could satisfy their desire in always be fond of new looks.

2. Development

At the end of 2015, US technological engineers finally conquered the conundrum that combines the solar energy and NT (Nanotechnology) into one small energy container. This means many battery using technologies can store much more huge amount of energy than user, which technologically speaking, could lowered the payment on users’ electric bill and also longer the batteries’ life spans.

Time firstly published this news on the Christmas special edition on December 24th, 2015. It wrote that the remarkable success was a huge step for human being on the way of scientific and technological development; it was a milestone for later technological advancement.

In later several years after this technology had been widely used, almost all battery using technologies have turned to add in this technology especially in mobile phone industry. The appearances of mobile phones have been changed, more creative ideas for mobile phone producers and more options for final users to choose. Motorola produced a super thin mobile phone Moto649 with a transparent screen, which is also the battery absorbing part, on the top of the phone. When the phone is not using, the screen part is penetrable and easy for carrying. Users can simply lock their phones on their key chains. This Moto649 starts a brand new era for mobile phones in considering more in kinesiology to be more suitable for human being in using technologies.

A great news was bombed after a long peace and the bottleneck in mobile phone industry in April, 2022. Consumers can now own self humanoid robots! The outlook of the robots had almost no difference with real human beings. It can smile with the corners of the mouth uptrend; its skin is also as elastic as real skin. This humanoid robot wholly changed the way people thinking about a machine.

No longer after that, Nokia888 appeared on the market, it was the first transformable mobile phone in the world and also the milestone in mobile phone technology. It follows the idea of kinesiology, combine the skin making of the humanoid robot, the Nokia888 could transformed into several forms to satisfied the users’ needs. It could be fold as a clip or wear as a bracelet. Users no longer have to worry about to leave a pocket for cell phones or the stolen of cell phones. Besides the merit of human touch and easy for carrying, it also works as a smart phone. It carried on the idea of a pocket computer, and made it simpler to operate.

3. Rationale

Using solar power to produce electricity is not the same as using solar to produce heat. Solar thermal principles are applied to produce hot fluids or air. Photovoltaic principles are used to produce electricity. A solar panel (PV panel) is made of the natural element, silicon, which becomes charged electrically when subjected to sun light. Energy conservation plays a crucial role for sensor networks. We propose to utilize solar power in wireless sensor networks, establishing a topology where, changing over time, some nodes can receive and transmit packets without consuming the limited battery resources. (Voigt,T. 2003)

Scientists are not only working on solar power, but also nanotechnology. It is said that advances in nanoscience and nanotechnology promise to have major implications in the upcoming decades. Knowledge in this field is growing worldwide, leading to fundamental scientific advances. And this will lead to dramatic changes in the ways that materials, devices, and systems are understood and created.

According to the development of these two perspective technologies, the possibility of making a solar-nanotechnology based battery has been hugely enhanced.

A robot called ‘Robovie’ has been developed. It has unique mechanisms designed for communication with humans. Robovie can generate human-like behaviors by using human-like actuators and vision and audio sensors. (Ishiguro, 2001) This research gives us the confidence that a real-human-look robot will not be only a dream. With the addition of nanotechnology, the iTransformer technology becomes a positive solution for future mobile phone.

A Brief Development History of Moblie Phone

Wenwen Chen


The primitive mobile telephones existed in the 1930s before the World War II. After the telephone was developed in the mid-1870s and radio at the turn of the century, it was natural to seek ways to combine the two, merging radio’s mobility with the telephone’s person-to-person capability and extensive network. (Tom Farley, 2007)They were specially converted two way radios used by government or industry, with calls patched manually into the landline telephone network. Many New York City fireboats and tugboats had this kind of radiotelephones at that time. (Tom Farley, 2005) Those radiotelephones were mobile, but they were big and clunky; and they were limited by the small range of the transmitter; the most serious problem is they only connected with fellow users.

On July 28, 1945 Time magazine said American Telephone & Telegraph (AT&T) was ready to manufacture “a new two-way, auto-to-anywhere radio-telephone for U.S. motorists.” It says millions of users could use the same channels across the country. A year after this print, on June 17, 1946 in Saint Louis, Missouri, AT&T and South-western Bell, began to operate MTS (Mobile Telephone Service). Motorola built the radios and the Bell System installed them. In 1960s, Motorola became a major supplier of pre-cellular car telephones. However, at that time, no one saw mobile telephony as a mass market, because the phones were big, expensive, and complicated to use, and the callers had little privacy. To make one three-minute call per day on the car phone, the cost per call would work out to about $8.00 in today’s money, exclusive of toll charges. (Tom Farley, 2007)Problems were listed by plenty of users, but there was no other way to connect to the telephone system when you were mobile. But all those imperfect promote the high speed development of mobile telephony industry.

In December 1947 Donald H. Ring outlined the idea that a true cellular radio system for mobile telephony in an internal company memo. The cellular radio elements were known as a network of small geographical areas called cells, a base station transmitter in each, cell traffic controlled by a central switch, frequencies reused by different cells and so on. (Tom Farley, 2005) Then in 1947, and for decades after, with this technology, more spectrums, more channels were essential to developing a high capacity in mobile telephone service.

In January 1969, the Bell System made commercial cellular radio operational for the first time by employing frequency reuse in a small zone system. By using public payphones, users could make telephone calls while moving at more than 160 kilometers per hour. In the same year, the first all transistor mobile telephones appeared: Motorola’s ‘Mark 12’. It marked the ending of the tube era for radio telephones. However, this transistor rig was still big and mounted in a vehicle.

In May, 1978 The Bahrain Telephone Company (Batelco) began operating the first commercial cellular telephone system, which had 250 subscribers in two simple cell schemes and can operate on 20 channels in the 400 MHz band, and used all Matsushita (Panasonic) equipment. (Tom Farley, 2005) Then worldwide commercial cellular deployment blossomed in the late 1970s and continued into the early 1980s.

In 1983, Motorola announced the world’s first handheld mobile phone, DynaTAC 8000X. But it took ten years for the DynaTAC to reach the market in 1973. Upon its release in 1983, the DynaTAC 8000X became an instant cultural icon, both as a status symbol for the rich and as an almost miraculous wonder: phone that a person could use anywhere. After the success of the DynaTAC, in 1984, Motorola followed up with the much small and lighter MicroTAC phone. This MicroTAC included a novel space-saving idea: it placed part of the phone’s hardware in a hinged section that could fold inward or outward as needed, thus reducing the size of the phone when it wasn’t in use. This concept lives on in many cell phones today. (Benj Edwards, 2009)

Although public mobile telephone history begins in the 1940s, only since 1990s have mobiles become low cost and used worldwide. In 1980s, many people think of the ‘car phones’; while in 1990s, they picture bag phones like the Motorola 2900. A bag contained a transceiver and battery, thus the users operated a much lighter corded handset. (Benj Edwards, 2009) Users could carry the bag on their shoulders. Because of the heftier batteries, bag phones could afford to transmit a cell signal with great power, supply long talk times and superior range. Therefore, even the bag phones remained bulk and the smaller phones are available on the market, the bag phones are still very popular.

In 1996, Motorola produced the 3.1-ounce StarTAC, which immediately proved popular and unfuential. (Benj Edward, 2009) The StarTAC allowed users to fold the phone in half when they weren’t talking on it. We now call this design ‘clamshell’, for the similarity to the way a clam opens and closes. A large percentage of mobile phones still use this design today.

After Nokia 9000i was born, the real beginning of our modern smartphone era started. Though many people give the honor of first-ever smartphone to IBM Simon. The Nokia 9000i truly was a pocket computer and a cell phone rolled into one. The Nokia 9000i could send and receive faxes, text messages, and e-mail, and also had limited Web access through 16-character SMS messages.

In 2002, Sprint and Sanyo released the first American cell phone with a built-in camera, the SCP-5300. The camera phone has a color screen, and the public went crazy for it. In 2004, Motorola broke the status quo of looking the same with the Razr V3. Motorola Razr V3 was a slim, slab-like clamshell phone with a large color screen, a stylish and flat keyboard, a built-in camera, and multimedia capabilities. It looks so cool and became wide popular.

Till now, mobile phones had become the dynamic and perhaps most important communication tool of our lives. After the year 2007, Apple rocked our world with its iPhone: it is a powerful pocket computer with excellent software, a game machine, and a multimedia-playback device. It also offers the ability of instant, high-speed access to the Web, e-mail, Facebook, Twitter, and YouTube, wherever you can find mobile phone coverage. The iPhone became a revolutionary device and other companies are already coming up with imitators.

Cell Phone in Contemporary Society

Cell phone and advanced cell phone in contemporary society

Cell phone has become a necessity of many people throughout the world. They had obviously taken an important role in keep in touch with family, friends, and business associates. Today’s cell phones with advanced technologies, are capable in not only placing and receiving phone calls and text messages, but also taking pictures, storing data, gaming, internet access, checking email, and even be used as walkie talkies, GPS, and MP3 players. These kind of high-end mobile phones which offer many advanced computing ability are called smart phones.

Smart phone, which is also called PEC-Phone (Pocket Entertainment Computer-Phone), is the trend of cell phones’ development. A smart phone may be thought as a handheld computer that integrated with mobile telephone. The demand of smart phone is the fastest growing segment of the cell phone market throughout the world.

With cell phones, users can contact with others even when they are moving around wide areas. By using advanced cell phones, sometimes with 3G or Wi-Fi technology, smart phones can help users do almost everything in almost everywhere. Cell phones are broadly used in all industries, for example, nursing, as I will mention later in this article.

Summary of the chosen article

In this article, the author supports the idea that smart phones will take a much more significant role in nursing, and will surely take place of PDAs or other certain kinds of devices.

Smart phone is a kind of new mobile technological device but rapidly successful developed in recent years. It has more advanced features than PDAs, which refers to personal digital assistants. The author said that although smart phones are not yet universally accepted in the healthcare sector, many studies have demonstrated an increased use of PDAs and other mobile devices in healthcare sector, and many experts predict that this technology will soon become an essential component of hospital operations.

Because a nurse’s job is highly information intensive, smart phones would allow them to input clinical data into the records of patients. However, though the smartphones may provide some help in the nursing workflow, the nurses still may not choose smart phones.

Because smart phones are not only be used in hospital settings, the attitude toward using a smart phone is affected by seven things according to the researches in this article. The seven factors are: the user’s compatibility with a smart phone, the observability of a smart phone, the relevance of a smart phone to the user’s job, the user’s personal demographics, the user’s personal experience, the user’s internal environment and the user’s external environment.

In conclusion, the author emphasized that smart phones are capable in changing the way healthcare is delivered, because smart phones integrated multiple and varied technological functions into a single portable and versatile device.

The positive  effect brought by this technology

  • Smart phones do help nurses much more than PDAs do. They are more easy and convenient to handle with, more portable and functional for them while dealing with different situation or record different data for the patients. Although, these kinds of smart phones may need to be settled more professional and specific for nurses.
  • The using of this kind of technological devices is increasing, not only in healthcare sector, but also in many other industries and societies.
  • Many people today have cell phones, because it becomes a necessity for people in the contemporary society. However, the emergence of smart phone breaks the boundary between cell phones and computers. They allows people dealing with daily works and communication together with only one portable device, without carrying heavy laptops although smart phones still cannot totally take place of computers.

New way out

Cell phones or the advanced ones we mentioned above as smart phones have many limits too. They have limited available screen size, and users often express discontent in the readability. They are high carbon and not very environmentally friend. Most smartphones in the market are big and heavy, which are not very suitable for carrying around.

If we can make a chip to instead a giant cell phone but with all functions inside it, it will make a more low-carbon environmental and more convenient way of communication.

This chip can be installed in all kinds of living goods. For example, glasses. Users can install the chip to their glasses, since they may wear the glasses every day, so it is the same that they carrying their cell phone every day.

The working principle of this chip is that users by pressing the installed chip, a vision of transparent screen will show up before the user, they can adjust the distance by pull or push the hologram, and the hologram works like a touch screen with vibrating or some kind of feedback.

This kind new technology may contain all the functions that a smart phone may have, and still solve the problem of screen size. The advanced chip with the features of low radiation, low-carbon, low-cost, saves lot natural resources and much more easier to carry around. It will become the trend of cell phone technology in the future.
