Wildlife experts in the US have a cunning technique to track "high-elevation" animals such as wolverines, lynx and gray wolves. Small survey stations known as "camera traps" use tempting scents to lure them in, before snapping a quick shot that can be used for research. The problem? The scent runs out after a few weeks, forcing conservationists at places like Woodland Park Zoo and Idaho Fish and Game to trek out and replace them manually. Microsoft researcher Mike Sinclair has been working with Dr. Robert Long, a senior conservation fellow at Woodland Park Zoo, and Joel Sauder, a wildlife biologist for Idaho Fish and Game, on a solution. The trio have developed an ultra-low power control processor, powered by lithium batteries, that's programmed to dispense just three millilitres of liquid scent through a tiny peristaltic pump each day. Just enough to lure the animals, but more importantly, the hardware can last six to nine months without any maintenance.
