+[[file:simscape-gravity/index.org][Manage Gravity within Simscape]]
+#+begin_quote
+Gravity can add some problems in multi-body simscape models: at the beginning of the simulation, some sag will be experience that may be unwanted.
+In order to start the simulation at equilibrium, few measured can be employed that are described in this document.

-* Nano Active Stabilization System
+[[file:test-bench-force-sensor/index.org][Piezoelectric Stack as Force Sensor]]
+#+begin_quote
+A part of a piezoelectric stack can be used as a force sensor.
+Then, the force sensors is collocated with the part of the stack used as an actuator and Integral Force Feedback control strategy can be used to add damping in the system.
+This is performed on an Amplified Piezoelectric Actuator
