The role of bio-inspired micro-/nano-structures in flexible tactile sensors

“…The development of bionic devices by imitating biological structures and properties has become one of the research hotspots. [46][47][48][49][50] Compared with traditional devices, tactile sensors prepared through a bionic strategy have enhanced properties such as sensitivity, working range and environmental adaptability. Some scholars have summarized and sorted out the material system of bionic sensors, the preparation technology and method of bionic microstructures, and the working principle of bionic tactile sensors, [51][52][53][54] but there is still a lack of attention to the rationality of the design inspiration of bionic tactile sensors and the a State Key Laboratory on High Power Semiconductor Lasers, Changchun University of Science and Technology, Changchun 130022, China.…”

Microsphere-Structured Protein Hydrogel Dielectrics for Capacitive Wearable Sensors

“…8 However, conventional dielectric layer materials for capacitive sensors are often made of silicone materials 9,10 and synthetic polymers, 11,12 which are problematic in terms of fit and biosafety. 13 Hydrogel-based materials have emerged as a preferred choice due to their simple preparation, high accuracy, fast response, good repeatability, and wearability. They are also well-suited for widespread applications such as artificial electronic skin and wearable devices.…”
