What to know:

  • Researchers have created a high-performing, inexpensive bioelectrical sensor by printing metals onto fabric.

  • The sensor detects electromyography (EMG) signals caused by muscle contractions, which can help inform the diagnosis and treatment of neuromuscular diseases.

  • Silver paste ― which is conductive and capable of detecting electric signals ― was printed into cloth by a team from the University of Utah and Gyeongsang National University.

  • Silver can cause skin irritation, so it was encapsulated in a layer of gold nanoparticles, which prevents it from touching the wearer's skin.

  • In addition to showing high performance in monitoring EMG signals in the bicep and fingers, the sensor stood up to multiple washings without a loss of performance.
