Penn State Researchers Develop Wearable Health Device

A new paper published in Microsystems & Nanoengineering explores how new tears- and saliva-sensing technology could help manage eye or mouth diseases. Led by Penn State University researchers, the wearable sensors placed near the tear duct or mouth would collect biofluid samples and deliver real-time medical data to a user’s smartphone or it could be sent to the patient’s doctor, according to the study. 

The work is being led by Huanyu  “Larry” Cheng, PhD, MS, Dorothy Quiggle Career Development Professor in the Pennsylvania State University Department of Engineering Science and Mechanics. Cheng previously published on a similar wearable skin patch that collects sweat and tests for pH, sodium and glucose levels, according to Penn State. 

The device will also administer medicine with a microneedle through the skin around the eye, mouth, or tongue.  Read more at news.psu.edu.
