Research Institution
This SBIR Phase I project is for an innovative, advanced microsensor for the detection of persistent organic pollutants in natural waters. The proposed sensor is a type of acoustic wave sensor fabricated via micromachining of anodic aluminum oxide, followed by coating with piezoelectric zinc oxide and analyte specific polymers. The sensor design (a flexural plate wave device) offers significant advantages for detection of very low levels of chemical species in liquids compared to surface and bulk acoustic wave devices. Phase I will demonstrate the feasibility of detecting low levels of persistent organic contaminants in water using the proposed acoustic sensor. A subsequent Phase II will extend the flexural plate wave design from a single sensor to multiple sensors in an array. Supporting instrumentation will be developed in order to fabricate a low-cost field portable instrument for the detection and quantification of chemical compounds in a marine environment.
