Electrode arrays for nerve stimulation in cochlear implants
ICsense has implemented direct nerve stimulation electrode arrays and nerve response telemetry for cochlear implants. The key challenge was to deliver an accurate charge to the tissue and be able to measure identical charges from the tissue. As the electronics are wirelessly powered, low power consumption is crucial. The response of the nerves and brain […]
40-channel DBS brain stimulation and recording ASIC
The ASIC is part of a novel DBS system with at least 40 electrodes for steering brain stimulation and brain recording. The ASIC is close to the electrodes, not part of the IPG/INS. For safety, AC power is transferred to the ASIC through a dedicated DC-AC-DC conversion scheme over the lead cable together with the […]
High-memory passive EPC Gen 2 RFID tags
In cooperation with Tego Inc. and Easics, a high-memory EPC RFID Class-1 Generation-2 UHF RFID compliant passive RFID tag is developed. This tag was selected by Airbus to perform maintenance management on their newest airplanes. The extended non-volatile memory of 32kbytes exceeds standard commercial tags (512 bits) and the interface capabilities are unrivalled. Moreover, the memory […]
