“…Flexible and wearable smart electronic devices have received a myriad of research interest because of their important applications in sports performance monitoring, healthcare diagnosis, human activity detection, and entertainment [ 203 , 204 , 205 , 206 , 207 , 208 , 209 , 210 ]. Nonetheless, sensors that respond to mechanical deformation that induces a change in the capacitance or resistance are certainly prone to microfissures or mechanical damage under repetitive deformation.…”
