The Surface Acoustic Wave (SAW) chemisensor. Part 1: A literature review
Abstract
The state of the art of microtransducers for chemical signals is presented. The sensors are grouped according to their operation mode, (semiconductor, optical fiber sensing, and piezoelectric crystal detection). Properties such as response time, sensitivity (detection limit), selectivity, reversibility, and durability are indicated. None of the chemisensors meets all the requirements for measuring equipment. Piezoelectric crystal sensors offer the best perspectives, followed by chemfets and optical waveguide sensors.
