Innovation technology: Researchers have developed a new, low-cost wearable device that transforms the human body into a biological battery.
How does it work?
The device is stretchy enough that can wear it like a ring, a bracelet, or any other accessory. It also employs thermo-electric generators to convert the body’s internal temperature into electricity.
In the future, wearable electronics can power without having to include a battery.
Advantages of this device
The devices can generate about 1 volt of energy for every square centimetre of skin space. Therefore, it is less voltage per area than what most existing batteries provide but still enough to power electronics like watches or fitness trackers.
Besides, it also can heal itself when damaged and is fully recyclable. Hence, making it a cleaner alternative to traditional electronics.
Previously, the experiment link with the design of electronic skin. It looks like real human skin. However, an external power source to work is necessary.
The speciality of the device
The device can make the whole system stretchable without introducing much strain to the thermo-electric material.
For instance, if you’re out for a jog. Your body heats up, and that heat will radiate out into the cool air around you. This device will capture that flow of energy rather than letting it go to waste.
The thermo-electric generators are in close contact with the human body, and they can use the heat that would normally be dissipated into the environment.
Boosting that power by adding in more blocks of generators.
In fact, it’s like putting together a bunch of small Lego pieces to make a large structure. In order to make more customization.
For example, a person taking a brisk walk could use a device the size of a typical sports wristband to generate about 5 volts of electricity.
The new devices are as resilient as biological tissue. If your device tears, for example, you can pinch together the broken ends, and they’ll seal back up in just a few minutes.
