Design of a mechanical stimulator for skin stimulation

A Pneumatic Stimulator was designed in coordination with the implantable electrodes for the external mechanical stimulation and to combine the stimulator with a recording system for nerve signals. It can be used in vivo experiments to investigate the reaction of sensory cells in the skin and the neural response on mechanical stimulation.

To observe the exact moment on which the mechanical part of the pneumatic stimulator hits the area of interest, an ultrasonic sensor was incorporated at the stimulation tip. The signal generated by the ultrasonic sensor is available as a TTL-level signal at the output of the stimulator. By varying the control gas pressure the hardness of the stimulation can be controlled. Also different front-ends can be adapted to the cylinder of the stimulator.
