The emergence of soft electronics that are tolerant to mechanical deformation has recently opened the rigid boundaries of solid-state devices. The advance in the field allows developing a 2-dimensional network of mechanically flexible sensors that can spatially map external stimuli, also known as electronic-skin. In this talk we introduce the concept of utilizing visco-poroelastic layer for electronic-skin applications that can yield visual readout of the locally applied pressure. The layer comprises a mixture of ionic transition metal complex electrochemiluminescence luminophore and ionic liquid within thermoplastic polyurethane matrix. Exploiting the visco-poroelasticity of the system, pressure-sensitive enhancement could be obtained from a simple device containing the mixed active layer sandwiched between two electrodes. Unlike previous works, our devices could visualize the local variation in the applied pressure without using spatially distributed arrays of unit pressure-sensors. |
