Technology Development

Sensors: Most tactile force sensors only detect pressure stimulus. However, simultaneous measurement of both pressure and shear forces is important for prosthetic hand grasp control, preventing slipping and enabling dextrous object manipulation.

Electrodes: There are currently several technologies to interface with the peripheral nerves, e.g. conventional nerve cuffs, longitudinal intra-fascicular (LIFE) electrodes, transversal intra-fascicular multi-channel (TIME) electrodes, Utah slanted electrode arrays and finally sieve electrodes.

Implantable Electronics: We aim to deliver a fully implantable 32 channel stimulation and recording system with wireless power and data transfer. The stimulator will be highly flexible and will target human safety requirements, while the recording will target low power (and low data rate) by using on-chip spike detection.
