Project Description
Nowadays there is an increasing interest in the field of implantable biosensors. The possibility of real-time monitoring of the human body from inside paves the way to a great number of applications and offers wide scenarios for the future. Power constraints of such devices can be relaxed by energy harvesters, devices exploiting natural or artificial power sources to assist implanted batteries.

By using inductive powering techniques, power can be transmitted wirelessly through the body tissues by exploiting a pair of inductors magnetically coupled. Moreover, inductive links are a well-suited solution for implanted biosensors due to the possibility to perform a bidirectional communication between the internal sensor and the external control devices.

The project proposed aims to develop a reliable model to describe the electrical properties of printed spiral inductors starting from the knowledge of their geometrical parameters and the surrounding environment. The model will enable the definition of one or more optimum geometry for different body implantations.

Project tasks

  • Definition of a reliable model for printed spiral inductors.
  • Validation of the model through measurements.
  • Understanding of the physical behavior of such devices and suggestion to improve their performance.

Eligibility Requirements

  • Analog design background.
  • Knowledge of  Printed Circuit Boards (PCB) design or willingness to learn.
  • Interest and motivation.

This project was supervised by Jacopo Olivo and Sandro Carrara.
