Digital Technology

"Necessity is the mother of invention." Spoken ages ago by the world's most influential philosopher, Plato, these words still hold true in the 21st century, that witnesses round-the-clock inventions in every branch of science and technology. Following are some technological breakthroughs that possess the potential of creating quite a stir in the modern age:

Dental training Robot
'Simroid' is Japan's latest invention. It is a humanoid robot that looks like a small Japanese woman. It assists dental students and allows them to treat their patients in gentler ways. It can sense the pain that results from a certain action by the dentist on his patient, and subsequently lets the dentist know about it. This is done with the help of a complete set of teeth that have sensors fitted in them, which would let the robot cry out in pain, if any action of the dentist hurts her. With the Simroid's artificial intelligence, people would not fear dental clinics, as the robot would train the dentist and try to cause minimum pain to them.

Technology that allows to see through walls and melt objects

Nokia, along with researchers from University of South Korea is working upon a technology that would enable users to see through walls and melt down the objects.

This invention makes use of augmented reality (AR) that overlays graphics on top of the video. It comes in three types:

X-ray vision, Melt vision (which has a more appealing look, giving objects a melt away look) and Distort vision (that changes the mobile video picture so that the objects that cannot be seen "bent" so the person could see them in the image).

Spray on Liquid glass

One of the most useful inventions in the field of nano technology, the spray-on liquid glass can protect any type of surface from damages caused by water, UV radiation, dirt, heat, and bacterial infections. It is transparent, non-toxic, flexible and breathable in nature, which makes its application even more diverse. For example it can be used to protect plants and seeds from all sorts of fungal and other diseases.

Silicon dioxide, obtained from quartz sand is one of its key ingredients. Researchers can adjust the levels of water and ethanol in the spray depending on the type of surface that needs to be covered with it. Its coating is just 100nm thick and yet it provides long lasting anti-bacterial effect. The spray, once applied can last for a period of a year, and can prove useful to many key industries as it can be used in clothing line, making all clothes stain resistant or in medical implants, catheters, sutures and bandage.

Currently, it is being used by a train company and a hotel chain in UK, and is being tested in Germany. Vulture-Unmanned Aircraft

An unmanned aircraft, with the ability to stay up in air for a continuous period of 5 years marks one of the most recent inventions of the world.

This project has been carried out by The United states' Defense Advanced Research Projects Agency (DARPA).

It will act as a pseudo-satellite, that would operate in the stratosphere, providing a 65 dB upgrading in communications along with increasing on- board sensor resolutions. This project is headed by NASA's project manager, Daniel Newman.

Currently, it is in the developmental stage and is trying to overcome problems of power supply during long missions, deterioration of materials due to long time exposure to stratospheric flight. Once fully developed, it would help in overcoming the traditional launch cycle of aircrafts that involves steps of launch, recover and maintain.

A Straddling Bus

A straddling bus would run down the streets of China, and would usher solution to its traffic related transport problems.

This bus works on Green technology based solar and electric energy, instead of using fossil fuels, making it an environment friendly option.

It would be 18 ft tall, 25 ft wide and would be able to seat around 1200 people. It would run on solar energy, captured by solar cells present on its roof. It would run at a speed of 25mph and would successfully be able to cut down traffic jams by 30%.

Car for blind people

Empowering the visually impaired members of society is a car that can be driven around by blind people. Based on Assistive Technology, it consists of Laser Sensors and Cameras that work as an eye. Apart from this, various instruments would be installed near the driver's seat that would inform and guide him about the required speed and direction that need to be taken.


It is Microsoft's new generation Cloud based Operating system that has the potential to completely rule out Windows.

Following the concept of visualization, Midori would be developed as a portable OS that could easily be mated with other applications.

It would solve all problems of security vulnerabilities, unexpected interactions among different applications, failures caused by errant extensions, plug-ins, and drivers.

Wireless Electricity

The idea of a world that receives and broadcasts electricity without wires is truly revolutionary. It has been created by engineers at MIT and members of University of Florida.

This technology would utilize the power of magnetic fields to provide electricity. Since magnetism does not harm the human body, it is safe. This technology has finds its application in almost every other device used, and currently it is being used in the form of wireless charging stations for homes, work stations or power broadcast systems.

Force Fields

Scientists are working on generating an artificial magnetic field, like Earth's Van Allen Belt that energizes the atmosphere and protects our planet from harmful solar radiation. Various approaches are being worked upon to develop this technology, varying from using plasma bubble to using a simple magnetic field generator that would consist of loops of wire with current running through them.

Currently in the development stage, a mission was undertaken in 1984 that used the same technology wherein a satellite named Active Magnetospheric Particle Tracer explorer produced a plasma cloud that successfully protected satellites from the solar wind, but once it ran out of plasma, it drifted away leaving the satellites unprotected. This aspect is being further worked upon.

Mind controlled computing

National Science Foundation and DARPA have been working towards developing a brain-computer interface that allows direct communication between a brain and any external device, taking the first ever human dive into cyborg-ism.

Its applications are limitless and it has the potential to benefit countless people worldwide, such as in the field of medicine it can be used to create implants that will restore vision, and make human telepathy possible.

Pocket sized medical scanner

General Electric has invented a pocket sized medical scanner, named VScan.

It is a thumb operated device that would empower doctors and paramedics by giving them the ability to perform ultrasounds right at the time of accident, without any bulky hospital institution.

This device can significantly uplift the quality of medical care worldwide.

Human Exoskeletons

Exoskeletons are human augmentation robotic systems that empower a person by allowing him to carry 200 pounds with minimal effort on any terrain.

It is helped on by an on-board micro computer that reads movements of the person wearing it and translates the motion into the suit, creating minimal resistance.

In the future, further developments are expected to link directly with the nervous system allowing quadriplegics and paraplegics the ability to control it without requiring muscle control.

These suits are collapsible and weigh about 31 pounds, enabling easy transportation and storing capability. These suits help on reducing stress on knees and back, helping a person to walk comfortably with load that might naturally be out of his power.

Square Technology

Square is a small plug-in attachment that is inserted into phones, allowing credit card payments. It is invented by Jack Dorsey, co-founder of Twitter and it uses a small scanner that plugs into the audio input jack on a mobile device. It basically enables all mobile phones to turn into cash registers for accepting card payments.
