P8.9 - Applying and Measuring Small Forces

Applying and measuring small forces is the final objective of our experiment described in a previous presentation. To apply a very small force in a controlled way, we need to know its point of application, direction and intensity. In this paper we describe a system constructed using piezoelectric actuators with a resolution at the nanometric level and flex plates made from HAVAR, a non-magnetic alloy. At first, we report the results obtained with a similar...
