Abstract

Facing the application requirement of flexible tactile sensors with high sensitivity

application of microstructure in preparation of high sensitive flexible tactile sensors are researched. Mathematical contact model for microdome structure is established

based on the piezoresistive theory and contact mechanics and combined with the ANSYS finite element simulation

the function relationship between contact radius and external force of micordome of flexible tactile sensitive unit is analyzed. The effect of geometric parameters of microdome structure on piezoresistive characteristics are studied. The research illustrates that the flexible tactile sensor with microdome structure is more conductive to enhance the sensitivity and linearity of the sensor

and can provide the reference for the design of flexible tactile sensor with high sensitivity.
