A Smart Sensor for Better Monitoring

A major challenge in self-powered wearable sensors for health care monitoring is distinguishing different signals when they occur at the same time. Researchers from Penn State and China’s Hebei University of Technology addressed this issue by uncovering a new property of a sensor material, enabling the team to develop a new type of flexible sensor that can accurately measure both temperature and physical strain simultaneously but separately to more precisely pinpoint various signals.

Ultrasound Waves Move Objects Hands-Free

University of Minnesota Twin Cities researchers have discovered a new method to move objects using ultrasound waves, which opens the door for using contactless manipulation in industries in which devices wouldn’t need a built-in power source to move. Read on to learn more.
