Outline of Final Research Achievements

Human can detect sub-um thick texture by measuring a vibration occurred between their finger prints and the texture with several tactile receptors which can measure the time variation of the contacting force: such as Meissner's corpuscle(FAI), and Pacini’s corpuscle(FAII). To figure out the efficiency of these tactile receptors and to realize their mechanical characteristics, we fabricated a skin-like tactile sensor based on the structure of Meissner's corpuscle. The sensor which can measure the time variation of the shear force. The sensor are composed by encapsulating the silicon piezoresistive cantilever inside a viscous liquid filter as similar as the structure of Meissner's corpuscle. By using this sensor we realized to measure a micro size and thick textile formed on different friction coefficient substrate.
