“…[ 342,343 ] Biocompatible, flexible, sweat‐activated batteries and biofuel cells have been introduced as alternative powering solutions for wearable multifunctional electronics. [ 342–344 ] In these devices, sweat acted as an electrolyte [ 342,343,345,346 ] and a biofuel [ 344,347 ] due to its high ion and lactate concentrations, respectively. For example, a flexible sweat‐activated battery patch yielded adequate energy to power soft multifunctional microelectronics (Figure 8i).…”

With the commercialization of first‐generation flexible mobiles and displays in the late 2010s, humanity has stepped into the age of flexible electronics. Inevitably, soft multifunctional sensors, as essential components of next‐generation flexible electronics, have attracted tremendous research interest like never before. This review is dedicated to offering an overview of the latest emerging trends in soft multifunctional sensors and their accordant future research and development (R & D) directions for the coming decade. First, key characteristics and the predominant target stimuli for soft multifunctional sensors are highlighted. Second, important selection criteria for soft multifunctional sensors are introduced. Next, emerging materials/structures and trends for soft multifunctional sensors are identified. Specifically, the future R & D directions of these sensors are envisaged based on their emerging trends, namely (i) decoupling of multiple stimuli, (ii) data processing, (iii) skin conformability, and (iv) energy sources. Finally, the challenges and potential opportunities for these sensors in future are discussed, offering new insights into prospects in the fast‐emerging technology.This article is protected by copyright.

“…Others have also reported similar SACs which are integrated with cotton yarn and demonstrated a stretchable battery in skin‐integrated electronics. [ 119,120 ] Integrating SACs into textiles and garments offers several benefits including intrinsic collection of sweat via wicking properties of textiles and ample surface area to integrate arrays of SACs in various series/parallel combinations for producing high power output. To achieve stretchability, biocompatible materials zinc (Zn; anode) and copper (Cu; cathode) were embedded in low‐cost water‐absorbable nylon fabrics as a functional layer, and a stretchable silicone shell‐based soft hydrophilic cotton containing potassium chloride (KCl) powder for capturing sweat was developed.…”

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

Conductive hydrogels have recently attracted extensive attention in the field of smart wearable electronics. Despite the current versatility of conductive hydrogels, the balance between mechanical properties (tensile properties, strength, and toughness) and electrical properties (electrical conductivity, sensitivity, and stability) still faces great challenges. Herein, a simplified method for constructing hydrophobic association hydrogels with excellent mechanical and electrical properties is proposed. The prepared conductive hydrogels exhibit high tensile properties (≈1224%), high linearity in the whole‐strain–range (R2 = 0.999), and a wide strain sensing range (2700%). The conductive hydrogel can realize more than 1000 cycles of sensing under 500% tensile strain. As an application demonstration, an underwater communication device is assembled in combination with polydimethylsiloxane/Triton X‐100 film coating, which successfully transmits underwater signals and provides warning of potential hazards. This study provides a new research method for developing underwater equipment with excellent mechanical properties and sensing properties.
