Our innovation:
New graphene solution-gated field-effect transistor arrays (gSGFETs) which are able to record infraslow signals alongside with signals in the typical local field potential bandwidth.
This device increases baseline stability that arises from the electrochemical inertness of graphene
Transistors can be scaled up from micro to macro scale as needed while different kinds of electrical contacts.
The gSGFETs are preferably placed on epicortical and intracortical positions.
The gSGFETs are fabricated using flexible substrate to overcome the difficulty in conforming to the geometry of different biological structures.
Graphene-transistor arrays allows several applications and deployments which range from subdural, epidural and intracortical devices to other placements in the brain, peripheral and cranial nerves, heart, blood vessels, spinal cord and other biological structures or non-invasive placement similar to an electroencephalogram.
Competitive advantages:
Flexible and versatile graphene-transistor array, it provides amplification of signals and high-fidelity recording in a wide-bandwidth. The device can be applied to other biological systems such as heart, kidneys, stomach, cranial nerves, and other regions.
To be determined during further development
Patient need addressed: monitoring brain signals (neural disorders)
