Wearable solar power generation

Is solar energy a good energy source for wearable devices?

Solar energy is also a kind of green renewable clean energy that is an ideal power source for wearable electronic devices 25, 26. Furthermore, hybrid energy harvesters that integrate capabilities of harvesting various forms of energy further improve the efficiency of energy harvesting and broaden the application scenarios 27, 28.

Can a self-powered solar generator power wearable devices?

Through structural optimization and heat flow management, this self-powered generator achieves a power density of 198 mW/m 2 in real-world outdoor wearable scenes and provides a robust solution for powering wearable electronic devices. 2. Results and discussions 2.1. Flexible multilayer selective solar absorber

Are wearable thermoelectric generators sustainable?

Wearable thermoelectric generators (wTEGs) have emerged as a sustainable power source by leveraging the stable temperature of the human body , .

How to design a wearable solar thermoelectric generator?

We designed a wearable solar thermoelectric generator (STEG) by combining BiTe-based TE legs printed on a PI substrate with a locally deposited solar absorbing layer, as shown in Fig. 1. The local solar absorber acts as the hot side and both ends of the PI substrate as the cold ones to produce a Δ T.

What types of energy sources are available for portable and wearable devices?

The energy sources available for portable and wearable electronic devices, such as mechanical energy, thermal energy, chemical energy, and solar energy, are extensive. According to the characteristics of these forms of energy, energy harvesting systems suitable for collecting various forms of energy have gained substantial attention.

How a self-powered wearable generator works?

Building upon the H-TEG, we propose a new integrated self-powered wearable generator. By combining the hollow sections at the top and middle of the thermoelectric device with an excellent solar absorber and a radiative cooler, this device can harvest energy from the human body/robots, sun, and cold space simultaneously (Figure S18).
