Stretchable and soft piezoresistive composites are appealing forapplication to tactile sensors, artificial skin, and wearable electronics. Theability of the composites to deform the geometries when they are strained canallow the electrical behavior of the composites to be manipulated. Althoughrigid metal and semiconductor inclusions have been utilized to createpiezoresistive composites, they limits the degree of mechanical deformation.Here, we utilized liquid metal inclusion into elastomeric foam substrate with3D open cell morphologies. The liquid metal is a fluidic conductor, thus it waspossible to infiltrate the liquid metal into the 3D interconnected pore,resulting in soft, stretchable, and shape reconfigurable conductive compositesthat can change shape and function in response to external stimuli. Interestingly,we found that this piezoresistivity of the composite can be positively andnegatively manipulated by adjusting the geometries of the liquid metal in thefoam. |
