This paper discusses the whisker sensor that can detect the surface features through a tracing motion. The sensor is composed of plural number of flexible beams with different natural frequencies, an adapter with strain gauge for each whisker, and an actuator for moving all of them. The mechanical vibration coming from the surface irregularities are picked up by each whisker and then converted into electrical signals through strain gauges. From the viewpoint of reducing the signal lines and cost, we feed all signals into one amplifier by connecting each strain gauge serially in the gauge box. Through the analysis of power spectrum, we estimate where the vibration comes from and how much irregularity is. We show the basic working principle of the sensor and experimental results to verify the idea.
