Abstract :
This work presents an energy-autonomous sensor module, entirely powered by a piezoelectric energy converter, which has the capability of interfacing to one or more passive sensors and sending the correspondent measurement signals over a radiofrequency (RF) link. The module general architecture is presented, and the strategy used for sensor signal conditioning and transmission is illustrated
