Journal ArticleDOI
On thermoelectric and pyroelectric energy harvesting
TL;DR: In this paper, it was shown that pyroelectric energy harvesting can achieve an efficiency of up to 50% of the Carnot efficiency with a limited temperature gradient due to the limited heat exchange.
Journal ArticleDOI
Pyroelectric energy conversion: Optimization principles
TL;DR: Practical implementation key points of pyroelectric energy harvesting are presented showing that the different thermodynamic cycles are feasible and potentially effective, even compared to thermoelectric devices.
Journal ArticleDOI
Experimental Duffing oscillator for broadband piezoelectric energy harvesting
TL;DR: In this paper, an experimental study of a Duffing oscillator exhibiting piezoelectric electromechanical coupling is presented, where a fast burst perturbation is used to accelerate the oscillator from the low solution to the high solution at a small energy cost.
Journal ArticleDOI
Piezoelectric vibration control by synchronized switching on adaptive voltage sources: Towards wideband semi-active damping
Adrien Badel,Gael Sebald,Daniel Guyomar,Mickaël Lallart,Elie Lefeuvre,Claude Richard,Jinhao Qiu +6 more
TL;DR: In this article, an enhancement of the synchronized switch damping technique on voltage source (SSDV) is presented, which allows fitting the mechanical braking force resulting from the SSDV process to the vibration level.
Journal ArticleDOI
Electrocaloric and pyroelectric properties of 0.75Pb(Mg1∕3Nb2∕3)O3–0.25PbTiO3 single crystals
Gael Sebald,Laurence Seveyrat,Daniel Guyomar,Laurent Lebrun,Benoit Guiffard,Sébastien Pruvost +5 more
TL;DR: In this paper, differential scanning calorimetry was used for measuring the electrocaloric response for different electric fields in the vicinity of the Curie temperature, where the maximum activity was found to be around the transition temperature.
