Perhaps, you have seen the matrix, witty you, a pat on the head: with the human body < p > < / P > < p > the National University of Singapore has successfully demonstrated a technology that uses the human body as a medium to charge wearable devices < p > you can charge any wearable device wirelessly through your body with an electronic device such as a mobile phone < p > the research has been published in nature electronics, which is also the first achievement of the existing research on such wearable devices < p > through the human body, one power supply can power 10 wearable devices < / P > < p > as you can see, the researcher's right wrist electronic watch has a transmitter below it & nbsp（ On the left wrist is the receiver（ receiver）。 < p > each contains a chip: < / P > < p > this is the composition of the system < p > transmitters can be placed near mobile phones, electronic watches or other electronic devices, and multiple receivers can be placed anywhere on the human body < p > then, the system uses the power of the power supply to couple through an individual & nbsp（ The process of body coupled power transmission provides wireless power for multiple wearable devices < p > (P.S. body coupling is a communication technology, which takes the patient's skin as a way of waveguide wireless communication) < / P > < p > the following figure is the schematic diagram of the system, which is an integrated circuit: < / P > < p > the circuit improves the recovered power level by adapting to the change of parasitic impedance of skin and electrode interface at the transmitter and receiver < p > in order to maximize the output power of the transmitter, dynamic impedance matching is needed < p > at the receiving end, in order to further enhance the power recovery and extend the power coverage to the whole body, a detuned impedance booster (DIB) and a bulk adaptation rectifier (bar) are proposed In addition, a dual-mode buck boost converter (dm-bbc) is proposed to ensure the maximum power reduction when the load changes < p > experiments show that a fully charged power supply can supply up to 10 wearable devices for more than 10 hours In addition, power can be obtained from the surrounding environment < p > because there are parasitic electromagnetic waves in typical office and home environments (such as laptops in operation) & nbsp（ parasitic electromagnetic，EM) 。 < p > using the receiver of the system to collect these electromagnetic waves can also achieve the function of charging the device through the human body < p > Future: smaller or even battery free wearable devices < / P > < p > to say the greatest benefit of using human body to charge wearable devices wirelessly, researchers said: < / P > < p > as one of the indispensable components of wearable devices, batteries are not only expensive, but also occupy a large volume < p > their unique system may save batteries in the future, so that manufacturers can make wearable devices smaller while reducing production costs < p > and if there is no battery limit, the next generation of wearable devices may be coming < p > finally, the team said that it will continue to improve the power supply efficiency of its transceiver system, hoping that any given power transmission device can meet the power demand of all wearable devices in the future

: No, thanks

, and netizens will make complaints about this research: it's a further step away from human being as a battery. The matrix is coming < p > however, there are still many people seriously discussing: < / P > < p > will the transmitter and receiver form an electric field in vitro, thus affecting other things < p > if you don't wear insulating shoes, how can you ensure that the current is not grounded < p > to this, someone gave the answer: it will not be grounded. Because in this DC circuit system, the current flows with the voltage difference, and the voltage difference is in your body. The ground is not a special conductor at this time < p > to ask whether you are willing to use your body to charge the device, many people have said: < / P > < p > "this is not good news." < p > "no, thanks." < p > maybe it interferes with the "vaccine chip" in the body And would you like to
