Published: March 3, 2023

Iontronic pressure sensors are promising in robot haptics because they can achieve high sensing performance using nanoscale electric double layers (EDLs) for capacitive signal output. However, it is challenging to both sensitivity and mechanical stability these devices. need microstructures that offer subtly changeable EDL interfaces boost sensitivity, while the microstructured mechanically weak. Here, we embed isolated ionic gel (IMIG) a hole array (28 × 28) of elastomeric matrix cross-link IMIGs laterally enhanced interfacial robustness without sacrificing sensitivity. The embedded configuration toughens strengthens skin by pinning cracks elastic dissipation interhole structures. Furthermore, cross-talk between elements suppressed isolating materials designing circuit with compensation algorithm. We have demonstrated potentially useful robotic manipulation tasks object recognition.
