1.electronic skin or E-skin
An natural circuit 10 instances thinner than a human pores and skin cellular, lighter than a feather, and that can be worn on the skin like an electronic tattoo
electronic pores and skin is a temperature and stress touchy, thin, electronic cloth that mimics human skin. just like human pores and skin, it is able to stretch and additionally heal itself. It uses stretchable sun cells advanced by means of a Stanford crew in February 2011 for electricity with an accordion-like microstructure that permits them to stretch up to 30% with none damage. The e-skin additionally consists of biological and chemical sensors along side pressure sensors. It sticks to the pores and skin due to Van der Waals forces which might be based totally on the attraction between molecules, rather than adhesives.
The e-skin turned into made through embedding sensors on a thin film after which setting the film on a polyester backing, similar to the only used in temporary tattoos. In July 2013, every other group at the college of California, Berkeley became capable of create an e-skin that lighting fixtures up when touched and receives brighter as the pressure will increase. a few of the potential applications of the e-skin are being able to reveal the vitals of a patient. Others are a robotic in an effort to be capable of hit upon disease or intoxication in a human and a video that can be played on the lower back of your hand. (source)
2.Li-Fi or light constancy
A excessive-velocity wireless communication gadget that utilizes household LED mild bulbs allowing information transfers 100 times quicker than WiFi and attaining speeds of up to 224 gigabits in line with 2nd.
The term “Li-Fi” become coined by using Harald Haas, a Chair Professor of mobile Communications at the college of Edinburgh, Germany, and the co-founder pureLiFI, to explain the idea of “wireless statistics from every light.” Li-Fi works by using switching the LED lights on and off at a completely high rate, too brief for a human eye to word, for you to transmit information.
The benefit of using seen mild over a ordinary WiFi’s radio frequency is that the spectrum is 10,000 instances larger and is expected to be ten instances less expensive. Researchers were capable of transmit records at a charge of 224 Gbits/2d, pretty loads better than the fastest broadband in 2013. since mild waves cannot penetrate the walls, Li-Fi is thought to be a ways more relaxed from hacking than WiFi. Li-Fi also does not require direct line of sight, and the mild reflected off the partitions can reap speeds of 70 Mbits/s.
3.wireless power Transmission
japanese researchers have succeeded in transmitting energy using microwaves and brought 1.eight kilowatts of power via the air, with pinpoint accuracy, to a receiver fifty five meters away
one of the main studies projects at the japanese Aerospace Exploration corporation (JAXA) has been sun power satellites (SPS), satellites which can harness the sun energy to be used on the planet.The strength would then be transmitted to Earth using either lasers or microwaves. but, lasers are considered impractical as they do now not paintings thru clouds. lately, JAXA changed into capable of deliver 1.8 kilowatts of energy to an antenna known as rectenna 55 meters away using carefully directed microwaves. The conversion of solar strength to DC, then to microwave, to DC once more, and ultimately AC is eighty% efficient, with out considering the lack of strength at some point of transmission. The enterprise is making plans on deploying a geosynchronous sun collector weighing 10,000 metric heaps at around 36,000 kilometers from Earth. via 2031, JAXA hopes to have a one-gigawatt industrial pilot plant operational.
