Book excerpt: [ANGLES] Here is presented a modest collaboration in a research project lead by Medical Devices Lab of NYU-Poly, whose goal is to design and build an implant to detect and block epileptic attacks. According to this, this developed work performs several essential parts to provide power at the implantable device, facing two main challenges: miniaturize the implantable device and maximize the efficiency of the wireless link. Following work starts analyzing what is the framework which makes the wireless link capable to transmit power from outside to inside the tissue. Once wireless link specs are determined, it is proposed to use a commercial chip to invert the DC voltage from a battery to AC signal, which is required for wireless transmitting. Finally, it goes deeper inside the brain IC designing a voltage regulator and an essential circuit to start up the system.
