CYBERHAND Neural Interfaces

Developed by: FhG-IBMT

The right side of the figure is the CYBERHAND sieve consists of 27 evenly distributed platinum ring electrodes. Each ring electrode has an area of 1884,96 µm2. The sieve has a diameter of 1.8 mm. The left side of the figure are two counter electrodes named as the proximal and distal counter electrodes

The External Control of CYBERHAND sieve electrode is a microprocessor controlled system that can select one ring electrode on the sieve at a time for stimulation or recording. For stimulation the external control has an inbuilt square pulse generator. It also allows the use of an external stimulation signal. In the recording mode, the information picked up by the electrodes can be transferred to a PC via the serial port of External Control.
