Researchers at the University of Utah's College of Engineering have developed a process that turns clothing fabric into biosensors which measure a muscle's electrical activity.

Chemical engineering assistant professor Huanan Zhang and his team have devised a method of taking ordinary textile made of a cotton/polyester blend and turning the fabric into sensors that measure electrical impulses generated from muscle movement.

The work is detailed in "Gold and Silver Nanocomposite-Based Biostable and Biocompatible Electronic Textile for Wearable Electromyographic Biosensors," published in the journal APL Materials. The study demonstrates that the approach can be considered for large-scale production of wearable electromyographic biosensors.

The process is resistant to repeated cycles in a washing machine, Zhang says.
