Sweat rate can provide the precautious signal of hyperhidrosis, hypohidrosis, and autonomic dysfunction. Currently, microfluidic and hygrometer-based sweat rate sensors are two types of available real-time sweat rate sensors. However, microfluidic device has issues of low temporal resolution, limited volume capacity, and surrounding artifact dependencies, while hygrometer-based devices also has overfilling and environmental artifact issues. In this work, we present reusable sweat rate sensor for continuous monitoring of sweat rate with novel sensor design.

2025

2D materials are among the most promising candidates for next-generation semiconductor devices due to their exceptional electronic transport properties and composition of a single atomic layer, which offers significant advantages for integration density. However, high contact resistance and challenges in doping present obstacles to their practical applications. In this work, we aim to explore various methods to overcome these issues and achieve technological breakthroughs that will enable these materials to become integral components in a wide range of applications.

Wearable, User-Centric Sweat Sensing Platforms with Scalable Fabrication

Noelle Davis
Ali Javey
2025

Sweat is a unique biofluid with noninvasive, continuous or near-continuous access, and potential for rich biomarker analysis. While current wearables are centered on heart rate-derived measures, sweat sensing offers an additional layer of insight, with metrics on hydration and psychological stress through sweat secretion rate and on other physiological parameters via chemical sensors. This dissertation addresses some key barriers to the integration of sweat
sensing into practical wearable systems: controlled uptake of fluid samples from dynamic, deformable skin surfaces, suitability for...
