A small device, called ‘Smart Stirrer’, performed a function of a conventional laboratory stir bar, has an integrated microprocessor and various sensors capable of wireless and autonomous report the conversion of properties of a solution. Results are sent to a computer over Bluetooth, and any changes notify the user wirelessly.

In the paper, ‘Monitoring chemistry in situ with the Smart Stirrer — a magnetic stirrer bar with an integrated process monitoring system’ published in the journal ACS Sensors, researchers from the School of Engineering, the Mathematics Institute and WMG at the University of Warwick present their innovative stirrer sensor.

The small device, called «Smart Stirrer,» performed a function of a conventional laboratory stir bar, has an integrated microprocessor and various sensors capable of wireless and autonomous report the conversion of properties of a solution. The advanced sensor stir bar is a capsule shaped magnet encased in plastic.

A beaker filled with a solution is placed on a platform that generates a rotating magnetic field, when the magnetic stirrer is placed in the solution it continuously rotates stirring the liquid.

The Smart Stirrer then monitors:

— Colour

— Transparency

— Conductivity
