Fraunhofer researchers have created a tiny yet powerful diaphragm pump that can deliver ambient air to gas sensors. The sensors are attached to a smartphone that warns a user of heavy exposure to particulate matter.
“Our smart pump measures only 25 sq mm, making it the world’s smallest pump. That said, it still has a high compression ratio,” said Martin Richter, department head of microdosing systems at the Fraunhofer Research Institution for Microsystems and Solid State Technologies EMFT, in a press release.
Richter also claims the pump could be used as a medical patch to continuously deliver small amounts of hormones and pain killers or even as an implant to regulate eye pressure in glaucoma treatment. It could also deliver scents through a headset for the gaming industry.
