TL;DR: Theoretical analyses of system-level bending mechanics show the advantages of WiSP’s flexible electronics, soft encapsulation layers and bioadhesives, enabling intimate skin coupling, and its physical attributes and performance results demonstrate its utility for monitoring cardiac signals during daily activity, exertion and sleep.

TL;DR: The latest technologies in multifunctional sweat sensing systems are presented with a focus on novel microfluidic designs, fully‐integrated wireless electrochemical sensors, and hybrid biochemical/biophysical sensing capabilities, creating real‐time physiological insights.

TL;DR: A skin-interfaced wearable microfluidic device and smartphone image processing platform that enable analysis of regional sweating rate and sweat chloride concentration is introduced and could improve the accessibility of physiological insights available to sports scientists, practitioners, and athletes to inform hydration strategies in real-world ambulatory settings.

TL;DR: This paper introduces a low-profile skin-interfaced system that couples disposable microfluidic sampling devices with reusable 'stick-on' electrodes and wireless readout electronics that remain isolated from the sweat, resulting in a cost-effective platform that is simple to use.

TL;DR: Quantitative analysis of sweat composition and dynamics currently relies on, first, capturing the sweat using disposable gauzes, absorbent pads, or microtubes followed by sample extraction through centrifuge and gravimetric tools and, finally, off-site analysis of the collected samples by leveraging standard laboratory-based analytical techniques.
