Abstract
An apparatus, system, device, and method provide the ability to measure forces a cell exerts on its surroundings. A platform is suspended across an opening using support legs. The platform is able to move horizontally in a plane of the opening. A piezoresistive strain sensor is integrated into the platform and measures strain induced in the support legs when the platform moves horizontally thereby measuring displacement of the platform.
