Abstract Surface electromyography (sEMG) can provide multiplexed information about muscle performance. If current sEMG electrodes are stretchable, arrayed, and able to be used multiple times, they would offer adequate high-quality data for continuous monitoring. The lack of these properties delays the widespread use of sEMG in clinics and in everyday life. Here, we address these constraints by design of an adhesive dry electrode using tannic acid, polyvinyl alcohol, and PEDOT:PSS (TPP).

Background Cerebral palsy (CP) is the most common childhood motor disorder, with an estimated 1 in 345 children identified with CP within the United States. It has a global incidence of 17 million and approximately 800,000 individuals are currently living with CP in the U.S. (Oskoui et al., 2013). CP results in weakness, delayed motor development, significant motor impairment ranging from weakness in one hand, to an almost complete lack of voluntary movement in all four limbs.

Introduction Spinal cord injury (SCI) is a life-altering event, resulting in loss of sensation and motor paralysis. In addition, persons living with SCI face a lifetime of impaired automatic (autonomic) bodily functions that affect every aspect of daily living.
