With about the size of an earplug and made of alumina alloy, the ability to properly study air and get some answers in relation to climate change may be within reach. This is of course all thanks to the scientists from Sandia National Laboratories who have announced these new tiny air samplers may yet help address the challenges and changes brought about by climate change.
The air samplers are capped with a tough inexpensive micro-valve where an electric pulse will cause them to open. A tiny hotplate built into the top of the chamber then heats the alloy adjacent to that opening. Because alumina is a type of solder, it liquefies, filling in the opening.
Because the air samplers are so small, simple and light, the researchers say that they could be put in locations that larger, traditional samplers could not. The flexibility allows the scientists to easily install them anywhere possible, offering a wider array of possibilities when it comes to studying the things behind climate change.
