Abstract
Skin torsionometers, methods and systems for using such skin torsionometers, and systems including a skin torsionometer, computing device configured to capture images, and an application (app) for determining the tautness of skin are described herein.
Claims16
A method for measuring tautness of skin comprising:
- providing a torsionometer comprising a shaft and a lower surface;
- providing a housing for rotatably supporting the shaft for rotational movement of the torsionometer relative to the housing;
- providing a sensor mounted to the housing and operably connected to the torsionometer to detect rotational movement of the torsionometer relative to the housing and connected to provide measured data to a processor;
- adhering the lower surface to the skin;
- rotating the torsionometer to thereby twist the skin until resistance from the twisting of the skin stops rotation of the torsionometer;
- releasing the torsionometer to freely rotate under torque from the deformed skin;
- measuring, by the sensor and the processor, recoil angular velocity of the torsionometer relative to the housing and associated with the releasing of the torsionometer;
- and
- determining, by the processor, the tautness of the skin based at least in part on the recoil angular velocity of the torsionometer.

A device comprising:
- a housing;
- a torsionometer comprising a shaft and a lower surface adherable to skin, the shaft rotationally attached to the housing to allow rotation of the torsionometer relative to the housing, wherein rotation of the torsionometer relative to the housing causes twisting of the skin when the lower surface is adhered to the skin;
- a sensor mounted to the housing and operably connected to the housing and the shaft to detect relative rotational movement between the torsionometer and the housing;
- a processor connected to receive a measurement signal from the sensor;
- wherein the sensor and the processor are configured to detect a recoil angular velocity of the torsionometer relative to the housing after:
- adhering the lower surface to the skin, rotating the torsionometer to thereby twist the skin until resistance from the twisting of the skin stops rotation of the torsionometer, and releasing the torsionometer to freely rotate under torque from the deformed skin.
