Wireless Power Transfer

In-vivo monitoring and treatment of key biological parameters can greatly assist in managing health and preventing disease. Implantable medical devices are increasingly an essential healthcare tool. Powering these devices by means of batteries or inductive coupling limits the range of possible devices to geometricaly large devices placed just below the surface of the skin. Our work has enabled deeper implantation depth and smaller (x100) device size by developing a new wireless power transfer regime. Currently we are extending this technology to enable even greater implant depths, integrating the receiving antenna on-chip to deliver more robust devices, and developing technology for distributed implanted devices.
