Can the human body achieve self-power supply in the future?

It is likely that micro-instruments will use the body's own power in the future.

The hot-hot "Mission Impossible 4" shows a bunch of near-future high-tech equipment that dazzles us. One of the retinal cameras allowed us to open our eyes to the eye: the function of a small slice to achieve photographing and transfer outside face recognition is already incredible. Where does it come from? The latest news provided clues to this question.

蟑螂 Create a "living battery"

Daniel Cherson, a chemist at Case Western Reserve University in Ohio, announced on the January 3 issue of the Journal of the American Chemical Society that his research team has used cesium to successfully create "living cells."

The project uses the blood sugar called trehalose, which was transformed during the feeding of alfalfa and other insects, as a fuel. The positive electrode is used to decompose trehalose, and a negative electrode is inserted to release electrons to generate an output current. After the electrodes were implanted in the larvae, the larvae still survived normally, and each larva generated a voltage of up to 0.2 volts.

According to sources, the US Department of Defense Advanced Research Projects Agency has taken a fancy to this project and intends to match Xiaoqiang with a microphone and pinhole camera to create a spy.

Seeing here, you may understand that the retina camera can be sourced locally and use human bioelectricity as an energy source.

"Living batteries" have been used by the forerunners as batteries are not the first of "living batteries". The earliest "living cell" was a biofuel cell that used an enzyme or a microbial tissue as a catalyst to convert the chemical energy of fuel into electrical energy.

In 2009, researchers at the Georgia Institute of Technology conceived a piezoelectric effect device that efficiently collects micro-energy, and tied this zinc oxide nanowire and a flexible plastic device to a hamster to take micro-dynamic power. The following year, implantable devices were installed in the peritoneum of laboratory mice to make glucose biofuel cells.

Today, trehalose biofuel cells that use helium to produce electricity have also come true. The two pests in the four pests will soon be transformed into treasures for the benefit of mankind.

The science and technology miracle that dream has become true as early as three years ago, some researchers claimed that can use the micro motive force inside the human body to generate electricity. Such as blood flow, heart beats and other low-frequency movements. Piezoelectric effects are used to obtain micro-power through zinc oxide nanowires for conversion. Use the heat that has been lost in the past as much as possible to provide power for some small portable devices.

We can imagine that in the not-too-distant future, whether you are sitting or lying down, the micro motive power generated by itself can generate electricity, and the convenience it brings is everywhere. The electricity generated by chewing is supplied to the miniature mobile phone between the teeth. The flow of blood supplies the speech recognition device in the ear, and the heart beats to provide a real-time physiological indicator.

It may take a few years before the retina camera that will be able to photograph and transmit through the blink of an eye in Mission Impossible 4 will become a consumer electronic product, but the face recognition function will be changed to smile recognition.
