FIG. 7.7 Schematic of (a) basic parallel plate electrostatic actuator ( Errando-Herranz et al., 2020 ) and (b) a comb drive for linear motion. Schematic of (c) a basic scratch drive actuator (SDA) ( Akiyama and Fujita, 1995 ). Step by step crawling motion of the actuator under pulse voltage input. (d) Pressing down of plate with rising voltage pushing the bushing forward. (e) Releasing of the SDA by falling voltage resulting in pulling the plate to right while pinning down the bush due to its shape. (f) Negative rise of voltage resulting in another pressing down of the beam resulting in the bushing moving to the left resulting in net rightward motion of the plate from the starting point. This process repeats for each half cycle. More about this image found in Schematic of (a) basic parallel plate electrostatic actuator ( Errando-Herr...

FIG. 5.3 A simple schematic to describe the working principle of an accelerometer. An accelerometer is a sensor which when mounted on a moving object measures the object's acceleration. Conceptually, an accelerometer is a spring-mass-damper system mounted on a base that moves due to external excit...

FIG. 7.11 (a) Gradient force between evanescently coupled freestanding waveguides ( Cai et al., 2012 ) resulting in bending. (b) Radiation pressure-based actuation using momentum transfer from reflected photons in a Fabry–Perot cavity to study the coupling of optomechanical effect with mechanical motion/vibration ( Kippenberg and Vahala, 2008 ). (c) Electrically and optically heated hot-arm cold-arm type actuator ( Serrano and Phinney, 2008 ).
