Recently, many researchers are interested in electronic skin (e-skin) that can visualization of mechanical stimuli for human-machine interaction. However, many mechanical visualization sensing devices have limitations in terms of low sensitivity and complicated fabrication processes. In this regard, electrochemiluminescence (ECL) materials have been exploited to form light-emitting based e-skin capable of mechanical sensing, because of their stability, simple process, and low operating power. Here, we propose the ECL skin exploiting a piezo-ionic effect, as an alternative strategy capable of transducing mechanical stimuli into visual readout. Our ECL material shows visco-poroelastic response to stress, which induces a change in the distribution of the luminophore in the film, as the piezo-ionic effect. As a result, Emission from our ECL skin is increased by the applied stress. The ECL skin are expected to provide new insights into the material design for the mechanical visualization. |
