Surface electromyography (sEMG) is widely used to investigate human motion including athletic performance. Baseball pitchers require very precise movements to pitch the ball to the strike zone, where the palm muscle plays a key role during movement. Recording the sEMG from the palm can help analyze motion during baseball pitching, however, currently available devices are bulky with rigid electrodes that impede natural movement of the wearer. Kento Yamagishi and a team of researchers in the School of Advanced Science and Engineering, Faculty of Sports, and Digital Manufacture and Design in Japan, therefore described a new skin-contact patch. The wearable device contained kirigami-based stretchable wirings and conductive polymer nanosheet-based ultraconformable bioelectrodes. The research team designed the device to address the mechanical mismatch between human skin and electronics and published the results on Nature Asia Materials.
