Abstract (en)
[origin: WO02099430A1] An assay system has a chamber that receives a test strip onto which a sample comprising an analyte has been placed. The chamber is in gaseous communication with a piezoelectric material that generates an electrical signal in response to a pressure change in the chamber that is caused by a reaction between the analyte and a reagent.
