제목 Biomimmetic Flexible Electronic Skin Sensors and Applications
초록 We introduce several biomimetic approaches to develop flexible electronic skins. Inspired by the fingertip skin, we demonstrate piezoresistive interlocked microdomes for the detection of normal, shear, stretching, and bending forces. We also demonstrate that ferroelectric skins with fingerprint patterns can discriminate static and dynamic pressure, vibration, and temperature. Mimicking the gradient modulus from epidermis to dermis layers, hierarchical polymers with gradient elastic modulus are suggested for triboelectric sensors capable of detecting human vital signs. Inspired by biological camouflage skins, we demonstrate conductive and ultrathin nanomembranes for transparent and skin-attachable microphones and speakers. Furthermore, we demonstrate a hierarchical nanoparticle-in-micropore architecture to enhance the mechanosensitivity of mechanochromic sensors. Finally, mimicking the human tongue, we demonstrate a hydrogel artificial tongue for astringency perception.
