An apparatus and methods for use in measuring the topography of a surface by contact which comprises a piezoelectric polymer film sensor, such as polyvinyldiene difluoride film, with a body portion and a tip portion, with electrically conductive films adhered to each principal surface of the sensor, and a non-conductive support restraining the sensor a fixed distance from the surface to be measured and with the sensor having an arcuate form when flexed by the surface.
