Toward the tactile presentation of hardness and softness, we have developed a rubber-like solid with branched polydimethylsiloxane ends cross-linked via a photoresponsive hexaarylbimidazole (HABI).
This material is characterized by its ability to soften upon irradiation with 430 nm light and to cure repeatedly after irradiation is stopped. Compressive properties of materials with controlled HABI number density for tactile presentation were evaluated. Under light irradiation, the compressive force at 1 mm compressive deformation was 0.71 N, whereas under no light irradiation, the force was 0.15 N, indicating a softening change
