Microsensor
0303001-126
[DEFINITION]
A generic term for devices that measure the physical or chemical
quantitiy, and are produced by micromachining.
[DESCRIPTION]
In micromachines, the first field to be developed and realized is
that of the micro-sensor. Microsensors include mechanical quantity sen-sors (measuring pressure,
acceleration, tactile senses, displacement, etc.), chemical quantity sensors (measuring ions, oxygen,
etc.), electrical quantity sensors (measuring magnetism, current, etc.), biosensors, and optical
sensors. In many micro-sensors, the detecting section containing the mechanism is integrated with
the electronic circuits. The advantages of micro-sensors are: 1) less environmental disruption, 2)
the ability to measure local states of small areas, 3) integration with circuits, and 4) less
operating power.
