Increase of the electromechanical coupling of piezoelectric vibration harvesters through lateral bars
David Gibus, Grégoire Forges, Hélène Debéda +2
To enhance the performance of vibration energy harvesters, it is essential to maximise the electromechanical coupling coefficient k of piezoelectric devices. This enables suf…
Modelling and design of highly coupled piezoelectric energy harvesters for broadband applications
D Gibus, P. Gasnier, A. Morel +2
This paper reports a method to design highly coupled piezoelectric energy harvesters with frequency tuning capabilities using nonlinear electrical techniques. A cantilever beam wit…
A Shock-Optimized SECE Integrated Circuit
Adrien Morel, Anthony Quelen, Pierre Gasnier +4
This paper presents a fully integrated, self-starting shock-optimized Synchronous Electric Charge Extraction (SECE) interface for piezoelectric harvesters (PEHs). After introducing…
Short Circuit Synchronized Electric Charge Extraction (SC-SECE): a tunable interface for wideband vibration energy harvesting
Adrien Morel, Adrien Badel, Pierre Gasnier +2
In this paper, we present a new harvesting interface, called Short Circuit Synchronous Electric Charge Extraction (SC-SECE). The SC-SECE strategy includes a tunable short-circuit t…
A 30nA Quiescent 80nW to 14mW Power Range Shock-Optimized SECE-based Piezoelectric Harvesting Interface with 420% Harvested Energy Improvement
Anthony Quelen, Adrien Morel, Pierre Gasnier +3
Piezoelectric Energy Harvesters (PEH) are usually used to convert mechanical energy (vibration, shocks) into electrical energy, in order to supply energy-autonomous sensor nodes in…
Bimetal-and-electret-based thermal energy harvesters - Application to a battery-free Wireless Sensor Node
S. Boisseau, P. Gasnier, S. Monfray +4
This paper introduces a thermal energy harvester turning thermal gradients into electricity by coupling a bimetallic strip to an electret-based converter: the bimetallic strip beha…
