The solution we propose is called SENSY: a unique device worldwide, which allows amputees, unlike currently available prostheses, to feel again from missing limbs. It is a neuroprosthetic device, which will be implanted within the residual nerves (in amputees), or healthy part of the nerves (in the case of neuro-damaged subjects), restoring the natural-like flow of the neural sensory information. It will enable subjects to feel natural and complete sensations from the missing or non-functional limb.

how SENSY works

The technology behind SENSY

SENSY is a hybrid neuroprosthetic device comprising the intraneural electrode for sensory nerve stimulation, implantable stimulator and smart controller, which can be connected with the sensors in the prosthesis or the sensorized glove or sock. The electrodes are made with the standard microfabrication process from the biocompatible materials, compliant and flexible at the same time, enabling long-term implantation within the residual nerves. Their optimized design results from the exact computer modeling and extensive experimental practice. Implantable neurostimulator is in bidirectional telemetry communication with external control chip. It is the “brain of the system” which is dedicated to the communication with the sensors of prosthesis or sensorized glove, on one side, and the implanted device on the other. Several options of intended use are possible: without prosthesis (neural sensory “pacemaker”), with sensorized prosthesis, or with the prosthesis with no sensors but with sensorized glove (hand) or sock (foot) over it.

We have been developing this technology for almost ten years. We have recognized expertise in algorithms development and their porting on chips, microelectrodes fabrication, animal and human clinical experimentation.
