Flexible and large area pressure sensors for human-neuroprostheses and human-neurorobotic interface assessment

Promising results on flexible and large area pressure sensors for human-neuroprostheses and human-neurobotic interface assessment are presented. Sensor arrays of 4?×?4 and 8?×?8 based on a plastic electronics concept, with a resolution of 1 and 0.25?cm², respectively, have been fabricated and characterized. The working pressure range is between 0 and 1?kg/cm² and the offset measured is around 0.03?kg/cm². The response time is around 1?ms. Using these sensor arrays, a sedestation–bipedestation field test by a pressure sensor integrated in a gait orthosis has been carried out in order to corroborate the medical application scenarios cerebrovascular accidents, spinal cord injuries and cerebral palsy.
