Can wearable energy storage devices be self-powered?

Charging wearable energy storage devices with bioenergy from human-body motions, biofluids, and body heat holds great potential to construct self-powered body-worn electronics, especially considering the ceaseless nature of human metabolic activities.

Should wearable energy harvesting devices be integrated with energy storage devices?

Integrating wearable energy harvesting devices with energy storage devices to form a self-sustainable power source has been an attractive route to replenish the consumed energy of the SCs/batteries, and thus, decrease the frequency of recharging or even enable a fully self-sustainable wearable electronics system. 12

Can human body energy be used to charge wearable electrochemical storage devices?

Human beings are living on sunlight-radiated earth, thus, harvesting energy from sunlight is a good compensation for human-body energy to charge wearable electrochemical storage devices, especially considering each human-body energy harvester requires specific conditions to deliver the best power output.

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 are wearable energy storage devices charged?

Wearable energy storage devices are charged by energy harvested from human biofluids. (A) The schematics of biosupercapacitor which combines a supercapacitor (SC) and a glucose BFC in one cell. Reproduced with permission. 105 Copyright 2014, The Royal Society of Chemistry.

Can flexible/stretchable energy storage devices be used as power sources?

The development of integratable and wearable electronics has spurred the emergence of flexible/stretchable energy storage devices, which affords great potential for serving as power sources for practical wearable devices, such as e-skin, epidermal sensors, individualized health monitors and human–machine interfaces.
