‘Solar Paint’ Produces Energy from Sunlight

A team from Australia’s RMIT University created a “solar paint” that generates its own energy. The sunlight-absorbing substance absorbs and splits water atoms, resulting in hydrogen that could someday be used to power fuel cells and conventional combustion engines.

High-Efficiency Power Converter for the Internet of Things

Researchers from MIT’s Microsystems Technologies Laboratories (MTL) have designed a new power converter that maintains its efficiency at currents ranging from 100 picoamps to 1 milliamp.

Internet of Things sensors will have to operate at very low powers to extend battery life for months, or make do with energy harvested from the environment. But that means that they’ll need to draw a wide range of electrical currents. Researchers from MIT developed a new step-down power converter that features a variable clock that can run switch controllers at a wide range of rates.

Self-Charging Battery Could Make Chargers Obsolete

New technology developed by Hydro-Québec and McGill University is capable of harvesting and storing energy using light – a self-charging battery. To create the light-charged batteries, a standard cathode from a lithium-ion battery can be “sensitized” to light by incorporating photo-harvesting dye molecules.

One of the biggest problems with computers is keeping them cool so they don’t overheat. University of Nebraska–Lincoln engineers developed an alternative energy source that would allow computing at ultra-high temperatures. The nano-thermal-mechanical device, or thermal diode, could be used in space exploration, for exploring the core of the earth, for oil drilling, or in applications requiring calculations and data processing in real time in places where computers have not been able to function.

PTC Heater Brings Greater Control for Hand-held Medical Devices and Disposables

Point of Care diagnostics devices, whether handheld or single-use, often require a brief application of tightly controlled heat. The disposable nature of these devices requires a low-cost component capable of delivering that heat reliably and safely. Heatron's new PTC heater solution uses a polymer-based heater technology that controls heat to within ±2°C of the target temperature, and reduces unit cost by eliminating sensors and applied controls.
