Outline of Final Research Achievements

To realize high-sensitive and shock-resistant tactile sensor, the sensing element was surrounded by dilatant fluid, which is soft against a static force and hard against an impact force. The applied static force was concentrated to the sensor, whereas the impact force was dispersed to the substrate. the shock-resistant nature was defined as the value obtained by dividing the maximum strain at the impact force by the strain at the static load. It has been experimentally shown that the shock-resistant nature of the sensor with dilatant fluid package was 2.3 to 16 times as large as that without the fluid.
