Analog and Mixed-Signal Design

The technical field of the project relates to sensors, such as wireless and battery-free sensors, for Remote Monitoring of Human Metabolism (HM). Taking advantage of their wireless communication capability, sensors in a wireless sensor network (WSN) may be positioned in places which are uncomfortable to reach, because no cables can be used for data communication and power supply. In some cases, no batteries are allowed to be used, as in the case of the sensors working in very high temperature environment or human body sensors. Despite the extensive activity in the area, further improved solutions are desirable. In this context, solutions are desirable wherein a Human Body Metabolism function to be monitored, may provide at the same time power supply and measurement functionality of the specific Human Metabolism parameters to be measured (e.g. Glucose, Lactate, Cholesterol, etc.).

This suggests to explore the feasibility of a measurement system of HM parameters, with the following characteristics:

• Battery-free, as it is self‑sustained, from the energy point of view, by harvesting the energy developed during the Human Metabolism.
• Has a time domain readout of the measurements. It is able to transmit the information (Human Metabolism parameters) through an Internet of Things (IoT) approach.
