We want to design a wireless system for measuring physiological parameters non-invasively. The system parameters will be obtained from the measurement of electrical (electrocardiogram (ECG)), and mechanical signals (ballistocardiogram (BCG)) of the body, acquired using a domestic scale and also through a node with an accelerometer sensor. The data acquired with a low-power microcontroller will be sent to a radiofrequency (RF) receiver connected to a PC, in which the measured signals will be observed. The project will study the effect of different mechanical interfaces in the measured signals and the feasibility of the integration of the different sensors in a wireless sensor network.
