Organic photodiodes can be much larger than their silicon counterparts. On the left is a silicon photodiode compared to two large-area organic photodiodes.

Researchers have shown that they can accurately assess blood loss by measuring seismic vibrations in the chest cavity and by detecting changes in the timing of heartbeats. That could lead to the development of a smart wearable device that could be carried by ambulance crews and medics and made available in emergency rooms and surgical facilities.
