Cochlear hair cell mechanics are typically probed using a flexible glass fiber. Fibers are individually produced and can vary substantially in their mechanical properties. The fiber is actuated using a macroscale piezoelectric stack and the fiber deflection is monitored optically, which both have a variety of limitations. We have developed micromachined silicon force probes that improve upon these characteristics.
