For the first time, objective, highly accurate measurements on the nail are possible in vivo.
In collaboration with Prof. Paola Perugini from the University of Pavia in Italy, Courage + Khazaka electronic have developed a patented method to analyse mechanical properties of nails.
This is an ideal solution for efficacy testing of nail care products as strengtheners and coats.
The extremely user-friendly software makes handling very easy. The nail is placed on a support in the unit constantly monitored by a built-in camera from the side, while a pressure applicators deflects the nail in smallest steps (0.001 mm).
The device features a high precision load cell which measures constantly the force needed for the deflection. A curve (force deflection diagram) of the measurement is displayed in real time.
Its slope is different depending on interesting mechanical properties of the nail:
- transversal deformation: elastic property of the complete nail
- longitudinal deformation: elasticity of the distal edge (flexibility) of the nail
- resistance to compression force: structural strength (firmness) of the nail
- distance measurement for the determination of nail thickness
The Nail StrainStress Meter is also very interesting for research on nail properties and disorders.
