Electromagnetic actuators

A miniaturized Fourier transform spectrometer for near-infrared measurements (FTIR, 2500-8330 nm) was developed at the Forschungszentrum Karlsruhe [120], Near-infrared measurements give information, for example, about the oil, water and protein content of liquids or solids. The dimensions of the detector chip are 11.5 x 9.4 mm, the device is essentially a miniaturized Michelson interferometer and it consists of a micro optical bench with beamsplitter, ball lenses, mirrors and the detector chip. The light beam is coupled in via a glass-fiber and an electromagnetic actuator. The signal is derived from the signal response of the detector by Fourier transformation. [Pg.587]

Another type of electromagnetic actuator is shown in Fig. 8 c. It consists of a deflectable membrane having a metal conductor and a external permanent magnet. A current applied to the conductor perpendicular to the magnetic field generates the Lorentz force. [Pg.172]

CMP of the combination of NiFe together with SU-8 as an insulating material has been used for the manufacturing of electromagnetically actuated MEMS optical microswitches [32]. [Pg.426]

A demonstrator has been built [20] to show the interest of the piezoelectric actuator in this technique (Fig. 6.31). When the vibration is in the range 100... 400 Hz, the required piezoelectric actuators are much more compact than any electromagnetic actuators. Secondly, an efficiency in the range of 50% has been demonstrated. [Pg.124]

In a similar implementation, an electromagnetic actuator was introduced in Judy and Muller (1996, 1997). This actuator consists of a torsional polysilicon beam, firmly fixed at both ends to the substrate, and an attached magnetic plate made of NiFe at the middle of the beam. When a magnetic field is applied by an electromagnet, a pure moment is induced and the magnetic plate is rotated out of plane (Figure 2.11). The electromagnet is actually a 10-turn coil... [Pg.70]
