Entanglement harvesting of accelerated detectors versus static ones in a thermal bath [PDF]
Phys.Rev. D 107, 045010 (2023), 2022 We make a detailed comparison between entanglement harvesting for uniformly accelerated detectors in vacuum and static ones in a thermal bath at the Unruh temperature and find that, for a small energy gap relative to the Heisenberg energy of the detectors, static detectors in the thermal bath can harvest more entanglement and possess a comparatively ...

Thermoacoustic energy harvesting [PDF]
Journal of the Acoustical Society of America, 2015 Thermoacoustics have a key role to play in energy harvesting systems, exploiting a temperature gradient to produce powerful acoustic pressure waves. As the name suggests, thermoacoustics is a blend of two distinct disciplines: thermodynamics and acoustics.

Development of a biomechanical energy harvester [PDF]
Journal of NeuroEngineering and Rehabilitation, 2009 Biomechanical energy harvesting-generating electricity from people during daily activities-is a promising alternative to batteries for powering increasingly sophisticated portable devices. We recently developed a wearable knee-mounted energy harvesting device that generated electricity during human walking. In this methods-focused paper, we explain the

Impact-Driven Energy Harvesting: Piezoelectric Versus Triboelectric Energy Harvesters [PDF]
Sensors, 2020 This work investigated the mechanical and electrical behaviors of piezoelectric and triboelectric energy harvesters (PEHs and TEHs, respectively) as potential devices for harvesting impact-driven energy. PEH and TEH test benches were designed and developed, aiming at harvesting low-frequency mechanical vibration generated by human activities, for ...
