Abstract
An inclination sensor includes a container in which an electrolyte liquid and a gas bubble are sealed. The container has a top member with a concave surface having a radius of curvature in a first direction larger than a radius of curvature in a second direction, perpendicular to the first direction. The concave surface is provided with two electrodes that are aligned in the first direction. An inclination of an object is measured by mounting the inclination sensor to the object and electrically detecting the position of the bubble as it contacts the concave surface, by passing a current through the liquid.
