Conventional lab-scale laser technology currently achieves this ultra low-noise, stable light via bulky, costly tabletop systems designed to generate, harness and emit photons within a narrow spectral range.

The tool acts like a satellite navigation system, but instead of guiding you to your hotel, it identifies the geographical source of microorganisms. This means you can use bacteria to determine whether someone has just been to the beach, got off the train in the city center or taken a walk in the woods. This opens up new possibilities within medicine, epidemiology and forensics.

Device comprises a hexagonal array of 19 actuators encapsulated in soft silicone. Device only uses energy when actuators change position, operating for longer periods of time on a single battery charge.
