Multi-harvesting smart solution for self-powered wearable objects
Résumé
Energy harvesting technology provides a promising alternative to batteries usage in low power systems. The integration of these solutions on the same silicon support is a real technological and technical challenge. This paper proposes a multi-harvesting fully-integrated system architecture combining AC and DC sources. Based on a MATLAB/Simulink model, the proposed system allows the calibration of an optimal solution. It is designed and simulated in 40 nm CMOS process, proving that using an AC source as second input, allows to start a harvesting system with very low DC source as main source.
