This article provides an overview of the recent advances in the field of skin‐worn tattoo‐based wearable electrochemical devices, including electrolyte and metabolite sensors, biofuel cells and batteries. Temporary tattoos are attractive platforms for fabricating skin‐worn devices. Body‐compliant wearable electrochemical devices on temporary tattoos couple highly favorable substrate‐skin elasticity with an attractive electrochemical performance. For example, tattoo‐based “skin‐like” sensors can be used for real‐time non‐invasive analysis of key electrolytes and metabolites, leading to remarkable sensing capabilities. Continued progress has been made also towards developing skin‐worn flexible energy harvesting and storage devices to power wearable health monitors and other devices. Key requirements and challenges that confront researchers in this exciting area of skin‐worn electrochemical devices are discussed.
