Recent developments in wearable and implanted devices have resulted in numerous, unprecedented capabilities that generate increasingly detailed information about a user's health or provide targeted therapy. However, options for powering such systems remain limited to conventional batteries which are large and have toxic components and as such are not suitable for close integration with the human body. This review provides an in‐depth overview of biofluid‐activated electrochemical energy devices, an emerging class of energy sources judiciously designed for biomedical applications. These unconventional energy devices are composed of biocompatible materials that harness the inherent chemistries of various biofluids to produce useable electrical energy. This article covers examples of such biofluid‐activated energy devices in the form of biofuel cells, batteries, and supercapacitors. Advances in materials, design engineering, and biotechnology that form the basis for high performance, biofluid‐activated energy devices are discussed. Innovations in hybrid manufacturing and heterogeneous integration of device components to maximize power output are also included. Finally, key challenges and future scope of this nascent field are provided.This article is protected by copyright. All rights reserved

“…Piezoresistive fabric strain sensors have attracted extensive interest in developing soft sensors as they provide high sensitivity with simple device and readout circuits. [ 37,38 ] A wide range of applications scenarios in biological motion monitoring have been presented including gesture recognition, [ 39 ] human posture monitoring, [ 40 ] Unmanned Aerial Vehicle control, [ 41 ] motion assist device control, [ 42 ] Virtual Reality / Augmented Reality virtual limb construction, [ 43 ] etc. Although previously reported approaches provide significant utility in this context, [ 44,45 ] most of them focus on pursuing either high sensitivity [ 46,47 ] or a large strain measuring range.…”

Advances in fabric strain sensors have established a route to comfortableto-wear flexible electronics with particularly remarkable permeability and low modulus due to their porous fabric microstructure. A key challenge that remains unsolved is to regulate the sensor response via on-demand design for a variety of application scenarios to sufficiently exploit the highest possible sensitivity. While recent reports have described a variety of options in varying the material and orientation of the overall fiber mat, the development of approaches where multiple sensors with different responses can be integrated on a single substrate without affecting macroscopic mechanical properties remains an area of continued interest. Herein, a simple mechanical strategy is reported, which plates the patterned functional material on the fabric mat at a pre-stretched state in the prescribed direction, and control of direction and prestrain forms either sensors with different responses or strain-insensitive interconnects. A systematic study has revealed the underlying mechanism of this strategy, which can serve as a guideline for the on-demand design and fabrication of fabric strain sensors. Demonstration applications in motion monitoring bandages and gesture recognition gloves illustrate capabilities in functional epidermal sensing devices.
