Keywords:laser displacement sensor, piconewton, MEMS

Measuring piconewton forces is required for not only physics but also biometry. We develop a laser displacement sensor, to which a principle of Michelson interferometer is applied, and a MEMS device, to measure a displacement generated by a force from sub-piconewton order to piconewton order.
