Ultra-thin, flexible probe provides neural interface that’s minimally invasive and long-lasting

Researchers have developed a tiny, flexible neural probe that can be implanted for longer time periods to record and stimulate neural activity, while minimizing injury to the surrounding tissue. The probe would be ideal for studying small and dynamic areas of the nervous system like peripheral nerves or the spinal cord.

Tracking Muscle Activity with Clothes on Your Back

In APL Materials, researchers have developed a bioelectrical sensor that is convenient and low-cost. The sensor measures electromyography signals that are generated in muscles when they contract and are useful for studying muscle fatigue and recovery, and they have the potential to inform diagnosis and treatment of neuromuscular diseases. The biosensor, made of silver paste with a layer of gold nanoparticles on top, is directly integrated onto a piece of clothing. The result was a detector that was both conductive and nonirritating to the skin.
