Wireless, Battery-Free, Subdermal Implantable Platforms for Transcranial and Long-Range Optogenetics

Case ID:

This invention is an improvement of current wireless subdermal implantable platform for long-range optogenetics and for transcranial implants without damaging brain tissue or using invasive surgical procedures. It uses capacitors and digital power management to deliver on-demand energy to the implant. This enables transcranial optogenetics stimulation and a longer range of operation in power transmitting arenas of larger volume.

Current devices on the market for fully subdermal implantable optogenetics tools that use wireless power delivery require invasive stimulus delivery, penetrating the skull and the disruption of the blood-brain barrier. Consequently, current devices can cause tissue displacement, neuronal damage and scarring and diminish operational area size. 

This technology will make it possible to create wireless, battery-free subdermal implants capable of delivering light-intensity optogenetics light stimulation that avoids damage to the brain tissue, simple surgical implantation, and enables new etiological grounded neuroscience experiments.
