Invent precise tools to produce the electricity that will power machines

The device generates energy from sweat and was made by a Chinese team, just wear it with the tip of a finger.

In a recent article published in the scientific journal “joule” A new highly advanced device has been introduced device Capable of converting sweat collected from fingertips into energy. Made by Team from researchers Chinese which has developed a small strap that is flexible and so thin that people can use it even while they are sitting or sleeping.

The “free energy” of sleep?
Wearable bioenergy harvesters that used to require a great deal of exercise to generate a small energy no longer exist!

In short, even Sweat It’s not getting rid of anymore, maybe soon Transformation In one of the most unexpected, effective and inexhaustible stocks energy At our natural disposal, especially now that we are in this period summer And heat can play an important role in our interests. It’s a bit like in the famous movie “matrix”, Directed by Sisters 1999 Wachowski.

Scientists from the University of San Diego, in California, row device As the most complete and functional human body energy collector ever, capable of generating 300 mJ per square centimeter without the need for mechanical push from the outside. A decisive step towards the future, which if properly exploited could turn into a turning point in the wearable electronics sector.

Will the newly invented little gadget be able to completely replace electricity?

Still not completely, but at least partially small tool It will be able to meet the energy needs. The team of researchers led by lu yin It is believed that most of this energy can be obtained during sleeping hours, moreover, “unlike other wearables that run with sweat – continues the expert – our solution does not require Playing sports NS Enter physical. I think this is the first step in making hardware wearable More practical, convenient and accessible to everyone. ”

Teacher nano From the same University of San Diego Joseph Wang He then adds that the device can be reused for any daily activity done with the hands that requires the use of touch, precisely because glands sweat inside Fingertips One of the fingers is more productive than the one in the rest of the body.

the small tool It is very easy to apply, just attach it to your finger with a simple patch and the carbon foam electrodes will absorb the sweat until it turns into electricity. In everyday life, of course, the most varied uses can be used, for example in a full night’s sleep the possibility of its production has been verified 400 mJ of energy, while spending an hour in computer Using the mouse will launch about 30.
