Smartphone Science

The smartphone that many of us use every day is one of the most advanced photonics devices ever made with state-of-the-art imaging and communications built-in. The links below show how smartphones are used by scientists as measuring instruments in applications from air pollution and light pollution, to adaptation as a microscope for measuring bacteria. Find out how you can use your own smartphone to perform scientific measurements with simple apps and add-ons.

Scientific Uses

Compact Microscopes for Your Smartphone
“Two winners of the 2009 Vodafone Wireless Innovation Project were compact microscopes that interface with a cell-phone camera. There is also a nanosensor-based detector for airborne chemicals that plugs into an iPhone. Although envisioned for field use, these devices highlight the possibilities of the technology.”

iSPEX: Measure Aerosols With Your Phone
iSPEX is an instrument that measures atmospheric aerosols with your smartphone. Although invisible to the naked eye, we inhale tens of billions of aerosols every time we inhale. Aerosol groups include sulfates, organic carbon, black carbon, nitrates, mineral dust, sea salt, or a combination of these elements. Despite their small size, they have a huge impact on our health and climate. The iSPEX smartphone attachment is revolutionary because it allows the general public to learn more about the presence of aerosols and their impact on the immediate environment.
