Photopower for microlabs

Miniaturized devices such as microsensors often require an independent, equally miniaturized power supply. Searching for suitable systems, Japanese scientists have now developed a fully integrated microfluidic device that produces hydrogen fuel and converts it into electrical energy based on photocatalysis. As they report in the journal Angewandte Chemie, it works fully autonomously and delivers enough hydrogen energy to power a microsensor for daily data transmission.
