A tactile sensor for robotic applications is described,
inspired by the mechanoreceptors in the glabrous skin of the
human hand, in order to replicate the sensory function of both
slow adapting and fast adapting mechanoreceptors. Strain gauges
were used for the slow adapting receptors, and polyvinylidene
fluoride (PVDF) film was used to replicate the fast adapting
receptors. A finite element analysis (FEA) model was used to
predict the output response of the PVDF film, and verified
experimentally. The PVDF film was observed to respond linearly
to mechanical stress and exhibited increased gain at higher
frequencies. “Ramp and hold” stimuli were applied to the tactile
unit sensor, and the PVDF film only responded at contact onset
and offset, similar to the response of fast adapting receptors. The
PVDF acted as a dynamic sensing element for the proposed tactile
sensor unit.
