Abstract [en]

This master thesis investigates how implantable devices can operate without the use of internal batteries. The idea is to be able to drive a circuit inside human tissue to i.e. monitor blood flow in patients. Methods such as harvesting energy from the environment to power up the devices and wireless energy transferring such as electromagnetic induction have been investigated. Implantable devices as this communicates wirelessly, this means that data will be transferred through the air. Sending data streams through air have security vulnerabilities. These vulnerabilities can be prevented and have been discussed. Measurements of the electromagnetic induction have been made with tissue-like material, to see how tissue affects the received signal strength indication levels. Optimization have been made to make printed inductors as efficient as possible by looking at the parameters that have an impact on it. This to get the most out of the inductor, while still keeping it small when it comes implantable devices. Smaller size is better for implantable device.
