Coloured SEM of a micromechanical accelerometer
Numéro d’image : 11894853
| Micromechanic accelerometer. Coloured scanning electron micrograph of a micromechanical accelero- meter. The interlocking 'teeth' at centre are able to move relative to one another. They contain inductors,devices which generate an electric current in response to a change in an magnetic field. During a high acceleration or deceleration,the 'teeth' move towards each other,causing a change in the magnetic field. The signal from the inductors is then amplified to activate another system,such as an air-bag in a car. This device has been manufactured,using the same techniques used to make silicon chips,at Cornell University,USA. Magnification: x350 at 5x7cm size. magnification: x560 at 10x12cm size | |
