A Charge Controlled Switched-Voltage Mode Neurostimulator: For effective, safe and efficient multi-channel intracortical visual stimulation

Development of a visual prosthesis has the potential to help millions of patients with visual impairment around the world. One approach of visual prostheses is intracortical stimulation, where electrodes penetrating the visual cortex are used to create small light dots in the patients visual field. Said therapy requires an implantable...

Safety Module for a High Frequency Arbitrary Waveform Generator

The goal of the REValUE Project is to design a test device which is able to stimulate nerve tissue with current driven, high frequency stimulation in the range from 1 to 15 kHz and 1 to 10 mA. The test device will be used in research to pudendal nerve blockage. This thesis describes the design process of a safety module for this device. The...
