Ultrathin, Highly Elastic Skin Display to Monitor Patient Vitals

An innovative ultrathin, elastic display that comfortably fits on the skin is capable of showing an electrocardiogram’s moving waveform recorded by a breathable, on-skin electrode sensor. This integrated biomedical sensor system together with a wireless communication module is known as "skin electronics," which can send biometric data to the cloud.

Fiber Optic Sensors that Dissolve Within the Human Body

As a first ever attempt, scientists have developed sensing elements called fiber Bragg gratings within optical fibers, formed to dissolve absolutely within the body. The bioresorbable fiber Bragg gratings can be adopted for in-body observation of bone fracture healing and for secure investigation of sensitive organs, for example, brain.
