Researchers at Duke University created a non-linear device that can convert a range of vibrations into electricity, improving efficiency over traditional linear devices. This technology has the potential to power small electronic devices, such as pacemakers and cardiac defibrillators, and even sensors in ocean buoys and spacecraft.
Engineers at the University of Leeds are developing a system to harness kinetic energy from soldiers' marches, capturing up to 15% of their foot-power to reduce pack weight. The project also aims to adapt radio equipment to run on low power budgets, enhancing soldier mobility and reducing fatigue.
The Air Force Office of Scientific Research is working on airborne solar cells using flexible films and transparent conductive electrodes. These cells have shown promise in powering small aircraft, and the team hopes to develop large, flexible DSSCs with higher energy conversion efficiency.
Researchers have developed a microgenerator that harnesses the heart's surplus energy to produce electricity for pacemakers and defibrillators. The innovative system, called SIMM, has shown promising results in increasing energy production with each heartbeat, potentially leading to longer-lasting devices.
Researchers identified pigment-binding protein CP29 as a valve regulating excess solar energy during photosynthesis. The study suggests that ambient pH levels can control the dimmer switch's opening and closing, with implications for designing artificial photosynthesis systems.
Researchers developed a new circuit that harnesses vibrations to generate up to 50 milliwatts of power, surpassing the output of simple energy harvesting circuits. The adaptive piezoelectric energy harvesting circuit can be used in various applications, including wearable devices, sensor networks, and smart home security systems.
