Abstract:
1. A sensor, comprising: a first polymer sensor element configured to generate a first voltage in response to a deformation thereof; a second polymer sensor element configured to generate a second voltage in response to a deformation thereof; a fixing member fixing a first end of each of the first and the second polymer sensor elements while electrically insulating the first polymer sensor element from the second polymer sensor element, wherein the fixing member includes a first insulating section provided between a first upper fixed electrode and a second upper fixed electrode each being connected to a front side of the first and the second polymer sensor elements, respectively, and a second insulating section provided between a first lower fixed electrode and a second lower fixed electrode each being connected to a back side of the first and the second polymer sensor elements, respectively; a weight attached to a second end of each of the first and the second polymer sensor elements; and a detector detecting an acceleration and an angular acceleration based on the first voltage derived from the first polymer sensor element and the second voltage derived from the second polymer sensor element.
