Abstract :
Batteryless wireless sensors are increasing their usefulness, making them cheaper and maintenance free. A system powered using ambient vibration energy and solar cells are presented, looking for a system with enough energy and autonomy. The paper presents the integrated power conditioning circuit conception proposed to work with both power sources, which have been modeled. The simulation of the full system with the electrical models of the sources allows us to analyze the performance of the system. In terms of the expected energy consumption the main parameters of the design are obtained.
