Our remedy is constantly generating heat to maintain its vitality. The body that falls below a certain temperature suffers hypothermia and begins to lose its vital functions. If it cannot be warmed, it cannot survive and dies. This energy, which enables us to live, will be used to charge wearable technological devices in the near future. A group of researchers from the University of Colorado wondered: Can human energy provide electronic power? It emerged as a result of the scientific research it could provide, and they proved this by developing a wearable device that converts body heat into electricity.



The researchers suggest that such devices made in the form of rings or bracelets could power wearable electronic devices in the near future. Scientists decided to better explore the possibilities of thermoelectric generators. The design of the device they developed includes modular thermoelectric chips, dynamic polyamine material and liquid metal electrical cables. The full name of the development will be “Soft plug-in with a hard motherboard”. The device can stretch up to 120% of its original size and allows it to be worn as a bracelet or ring. An interesting feature is the ability to heal itself. If the device breaks anywhere, it is enough to press its ends together so that they stick together.

Another important feature is that when the user needs more energy, they can easily combine two or more thermoelectric generators to generate more electricity. According to the developers, walking at a high pace will generate electricity with a voltage of about 5 volts for a fitness bracelet-sized device. The ultimate goal of the developers is to be able to create a wearable device like a battery-free fitness tracker. This will be a very interesting technology that could be implemented in commercial devices over the next decade.
