Device for system, particularly retina implant for stimulating nerve cells with passive membranes, has receiving unit for receiving biphasic stimulation signal indicating predetermined charge amount

摘要

The device (100) has a receiving unit (102) for receiving a biphasic stimulation signal (108) indicating a predetermined charge amount. A generating unit (104) generates multiple charging pulses (110), which temporally follow each other based on the biphasic stimulation signal, such that a total charge amount of multiple charging pulses corresponds the predetermined charge amount. A stimulating unit (106) stimulates the nerve cells with the passive membranes based on the multiple charging pulses. The generating unit generates multiple charging pulses by discharging a charge storage. An independent claim is included for a method for stimulating nerve cells with passive membranes.
