A generic term for sensors that use organic substances in the device, that are intended for measurement of organism related subsystems, or that mimic an organism.

A typical biosensor consists of the biologically originated specific material such as an enzyme or an antibody that identifies the object of measurement and the device that measures a physical or chemical quantity change related to the identifying reaction. A semiconductor sensor or any of various types of electrodes (ex. ISFET, micro-oxygen electrode, and fluores-cence detection optical sensor) prepared by silicon micromachining tech-nology can be used as this device. Biosensors are used for blood analysis systems, glucose sensors, micro robots, and so on.
