A Multielectrode Layout for High Reliability of Flexible Piezoresistive Sensor: One Stimulus Signal to Three Sensing Signals

“…14−19 For example, Wang et al improved the mechanical properties of flexible electrodes by adopting the tetra-chiral structure with a serpentine connection. 14 Kim et al improved the bending performance of electrode thin films for highly flexible devices by optimizing the size of conductive silver nanowires and substrate thickness. 15 Li et al significantly enhanced the tensile performance of electrical interconnects in flexible sensors through a secondary soft packaging strategy.…”

“…The most common form of failure mode in flexible sensors is that the flexible electrodes used for electrical interconnection crack or even break during the continuous bending process, , causing the sensor to be unable to output the sensing signal. Therefore, researchers usually optimize the structure and materials of the electrical interconnect in devices to improve the reliability of sensors. − For example, Wang et al improved the mechanical properties of flexible electrodes by adopting the tetra-chiral structure with a serpentine connection .
