Stretchable, Soft and Variable Stiffness Elastomer foam with Positive and Negative Piezoresistivity Enabled by Liquid Metal Inclusion |
| 초록 |
Stretchable and soft piezoresistive composites are appealing materials for application in tactile sensors, artificial skin and wearable electronics. The ability of the composites to deform the geometries when they are strained can allow the composites to manipulate the electrical behavior. Here, we utilized liquid metal inclusion into the elastomeric foam substrate with 3D open cell morphologies. The liquid metal is a fluidic conductor, thus it was possible to infiltrate the liquid metal into the 3D interconnected pore, resulting in the soft, stretchable and shape reconfigurable conductive composites that can change shape and function in response to external stimuli. Applying strain can enable the deformation of the liquid metal, generating changes of the electrical resistance. Interestingly, we found this piezoresistivity of the composite can be positively and negatively manipulated by adjusting the geometries of the liquid metal in the foam. |
