Empirical Modeling of a Squeeze Film Haptic Actuator

Yves Perriard, Miroslav Markovic, Christophe Winter

In the analysis of squeeze film haptic tactile feedback actuators, attention is focused on establishing an empirical model of the force generated on the user's finger. The model is based on finite-element simulations which take into account the real motion ...

Haptic Tactile Interface (HTI): Design of the Power Supply Stage

Yves Perriard, Christophe Winter

The driving electronics of an haptic tactile interface (HTI) is presented. The stability of its linear power amplifier under the capacitive load of the HTI piezoelectric actuator is analysed and ensured. As the HTI actuator is a resonant one, a topology to ...

Optimal design of a squeeze film actuator for friction feedback

Yves Perriard, Christophe Winter, Yoan René Cyrille Civet

Sense of touch belongs to one of the five Human Senses. Whereas blind people largely use feeling in everyday life, sighted person mainly focus on hearing and vision. However, haptic interface started being introduced in customers applications, such as smar ...

Modeling of the air film pressure for a haptic touch actuator

Yves Perriard, Christophe Winter

In the scope of haptic touch feedback actuators, we discuss the phenomenon of creating the haptic experience by squeezing the air film between the user finger and the actuator. The focus is given in the modeling of the squeeze film effect. An existing anal ...
