Soft reconfigurable logic gates with high-frequency electrical switching.

ABSTRACT: The development of functional soft materials has motivated replacing rigid electronics with stretchable logic structures. However, soft logic gates for macroscopic soft robots usually operate at low frequencies (<5 hertz). Here, we present high-frequency soft logic gates based on soft electric switches with ultralow latency (2 milliseconds). Fast switching is achieved using a tailored piezoresistive material-graphite frameworks (GFs)/polydimethylsiloxane (PDMS) and dielectric elastomer actuators (DEAs). The GFs/PDMS strip exhibits a large resistance change within ~0.01% strain, allowing soft logic gates to operate up to 100 hertz. A soft oscillator is further developed using feedback control with a soft NOT gate and achieves autonomous deformation across ~1 to 78 hertz, demonstrating actua
