SiP power management unit with embedded temperature sensor powered by piezoelectric vibration energy harvesting

Nowadays, there is an important interest in smart wireless sensors. A key point in their development is the way they are powered. Piezoelectric energy conversion can be used for such purpose. In this paper, a novel architecture that combines in a single integrated circuit the power conditioning circuitry needed to use piezoelectric energy conversion and an embedded temperature sensor is presented.
