Smartphone's Transformation into a Dual Spectrometer
Prof Abbas Jamalipour in collaboration with Prof John Canning at the School of Chemistry and PhD student at EIE, Md Arafat Hossain, are working on the use of mobile phones for monitoring water pollution using 3D printed custom-made attachments to the phone.
One of their recent works, for which a patent has been applied for, and published in the IEEE IoT Journal and Journal of Optics Letters, built an inexpensive and portable functional dual absorption and fluorescence spectrometer combining a smartphone and its set of electronic sensors (and CMOS chip) and a 3D printed enclosure.
The key challenge for the scientists was to build a "lab-on-a-phone" that was completely self-contained, with the phone’s battery, which can easily be charged anywhere with access to electricity, powering the entire system. The dual functionality also contributed to further reducing the cost of the device, while increasing the range of possible applications.
