ABSTRACT:
This invention relates to a chemical sensing device for detecting an analyte. The device comprises a light source; at least one luminescent reagent which is capable of luminescing when irradiated by the light source wherein the luminescence of the luminescent reagent is modifiable by the analyte thereby changing the generation of heat, which change in heat generation is proportional to the concentration of the analyte, a transducer having a pyroelectric or piezoelectric element and electrodes which is capable of transducing the change in heat to an electrical signal, and a detector which is capable of converting the electrical signal into an indication of the concentration of the analyte. The invention also relates to a method for detecting an analyte.
