Transducer for reference arrangement with thick-film resistors as a strain sensors

摘要

Pointing cursor control device for controlling a computer screen cursor includes a rigid base for the posts, the lateral and the thick-film resistor and a post on the side of the post that acts as a strain gauge for detecting the forward or backward bending of the post. The thick-film resistor varies depending on the resistivity of a piezo-resistive strain. Two resistive dividing network is formed, a network having a left and right of the resistor is detected the X- axis, and warp, and the other network having a front and back of the resistor detects the Y- axis warp. The voltage division by the network moves the cursor to the X and Y coordinate on the computer display screen hameuroseo forming a cursor-control signal is processed.
