Self-Powered Sensor for Harvesting Magnetic Energy

Because it requires no battery that must be recharged or replaced, and because it requires no special wiring, such a sensor could be embedded in a hard-to-reach place, like inside the inner workings of a ship’s engine. There, it could automatically gather data on the machine’s power consumption and operations for long periods of time.

Stretchable Micro-Supercapacitors to Self-Power Wearable Devices

A stretchable system that can harvest energy from human breathing and motion for use in wearable health-monitoring devices may be possible, according to an international team of researchers.

Optimize Charging for Maximum Solar Energy Harvesting

There is no one-size-fits-all answer. If you need the least expensive option, direct charging works. If you can spend more, you can opt for a PWM circuit. If the price is secondary and you need the absolute best performance, a true MPPT may be the best solution for your application.

System for Flight Control of Hypersonic Aircraft

Researchers have designed an electrode-based system for guidance, navigation, and control of aircraft or spacecraft moving at hypersonic speeds in ionizing atmospheres.

Biofilm Harvests Energy in Evaporation

The biofilm has the potential to revolutionize the world of wearable electronics, powering everything from personal medical sensors to personal electronics.

Circuit Generates Clean, Limitless Power from Graphene

The chip could provide low-voltage power for small devices or sensors.
