Skin Rheometer

Goodyer Skin Rheometer
An instrument for measuring the flexibility of skin tissue, the Goodyer skin rheometer takes advantage of modern actuator technology and electronic measurement and control techniques to give improved accuracy and reliability over previous equipment used by the cosmetics industry to investigate skin rheology.  At the heart of the system is a load cell sensitive to the small forces generated.
The signal from the load cell is used in a feedback controlled servo system. In practical terms, this means there is no need for a near frictionless system, and therefore no need for an air bearing. Motion is obtained using a servo motor, gears and leadscrew; conventional actuator technology.
