Long-distance and low-attenuation magnetic energy focusing technology for deep-tissue wireless powering

Fully implantable electronic devices such as cardiac pacemakers, cardiovascular monitors and deep brain stimulators, have been widely developed in medical monitoring, diagnosis, and treatments. Existing implantable devices are based on power supply through replaceable batteries, self-powering supply, and wireless power transfer. The key challenge for disposable batteries is the limited life, which requires intermittent replacement via surgery, resulting in non-negligible health risks and medical costs.
