Photonic Radar Monitors Breathing from a Distance
Engineers at the University of Sydney have developed a photonic radar that allows them to monitor breathing rates without the need to attach equipment to a patient’s skin. Wired or more invasive systems may not be suitable for everyone –...

Nanomagnet Patch Measures Muscle Movements
Researchers at UCLA have developed a wearable patch that can measure muscle movements in underlying tissues. The patch contains nanomagnets, and movements in underlying muscles can deform the resulting magnetic fields, creating an electric...

Wearable Ultrasound for Deep Tissue Monitoring
Researchers at the University of California San Diego have created a wearable ultrasound system that can monitor deep tissues, as far as 16.5 cm (6.5 inches) below the surface of the body. Moreover, the team employed a machine learning...

Pencil-on-Paper Wearable Sensor
Researchers at Penn State have developed a low-cost, wearable sensor using pencil-on-paper technology. This approach involves depositing graphite (pencil ‘lead’) on paper that has been treated with sodium chloride, to create a conductive,...

Cell Culture Chamber Mimics Mechanical States of Disease
Researchers at the University of Göttingen in Germany have developed a cell culture chamber that lets them culture tissue samples, mimic the mechanical conditions that tissues experience in various disease states, and closely monitor tissue...

Chest Wearable Provides Key Heart Measurements
Researchers at the University of Texas at Austin have developed a new chest wearable that can obtain both electrocardiogram and seismocardiogram data from the underlying heart. While basic ECG can be monitored via smart watches, no other...
