    A new kind of wearable health device would deliver real-time medical data to those with eye or mouth diseases, according to Huanyu ‘Larry’ Cheng, Dorothy Quiggle Career Development Professor in the Penn State Department of Engineering Science and Mechanics (ESM).

    Cheng recently published a paper in Microsystems & Nanoengineering on new micro- and nano-device technology that could revolutionize how certain health conditions are monitored and treated.

    “We sought to create a device that collects both small and large substances of biofluid...
