Colorimetric sensors are easy-to-use devices that can reveal information, such as humidity, acidity or the concentration of certain chemicals, through color changes and an intuitive interface.

The Central University of Kerala has created a paper-printed strip-based colorimetric sensor that will help patients to detect and quantify variation in sodium levels sitting at home.

New colorimetric sensor arrays on disposable test-strips read by hand-held devices allow for their rapid, inexpensive, and sensitive identification by their chemical "fingerprints".

The colorimetric sensor array (Shoe photo: Rama) The array only reacts to TATP, so factors such as humidity or the presence of other chemicals won’t affect the readings.

A research team develops a real-time humidity sensing optical sensor. The response time of the new sensor is 10,000 times faster than the conventional sensors and can be mass-produced at low cost.
