Chevron thermal actuator
WebSemiconductor thermal sensors are available as temperature sensor ICs. These ICs detect the temperature variation from the change in output quantities such as current, voltage, resistance, etc. Semiconductor thermal sensor ICs are highly accurate and linear over the temperature range of 55℃ to 155℃. Webdevices, a number of thermal actuators are typically connected in series [3]. Chevron type actuators [4], as shown in Fig.1 a, provide an even larger displacement, but such a single beam like device is difficult to integrate into a system. Here we report the development of a new type of planar microspring (P-spring) thermal actuator. Finite
