AAAS: "Wildlife tracking collar powers itself as animals roam." Replacing batteries in animal tracking devices time-consuming for wildlife scientists + stressful for animals. "[New] approach could help researchers monitor animals across entire life spans, making things easier for both." Many trackers solar-powered, but these don't work for nocturnal or aquatic creatures, nor species living in forests or caves. 'Nonrechargeable lithium-ion batteries—heralded by manufacturers as lasting for decades—another option, but field experience shows very hot or cold temperatures considerably shorten their life spans.' Biologists at Natural History Museum of Denmark looked at a Swiss smartwatch powered by a tiny generator that converts the wearer’s movement into an electromagnetic current that powers the device. At the Max Planck Institute of Animal Behavior a tiny generator was designed which harvests energy from side-to-side movement. "As a pendulum within swings, it generates current by sliding a ferromagnetic ring across a copper coil." The energy is stored in a lithium supercapacitor, which is capable of 40 times as many charge cycles as a standard lithium battery. 'Researchers packaged their new battery with a low-power GPS tracker, accelerometer, and a tiny computer inside a waterproof, fang-resistant case.' The schematics for the device are in the paper + freely available. Wonder if we could persuade our grandchildren to wear one. #trackingdevice #wildlifeonearth

Hidden #Chinese #trackingdevice 'found in UK Government car' sparks national security fears

Die Entdeckung wirft ernste Bedenken hinsichtlich der nationalen Sicherheit auf, da hochrangige Politiker eine dringende Überprüfung der "systemischen Bedrohung" durch chinesische Geheimdienste fordern.

Und über whatsapp u tiktok aufklären. Russen haben wegen ähnlichen Vorfällen ihr Leben vertan.
