ABREX®-A

Fingertip abrasion tester for your touchscreen

If you want to have further information or would like to submit a demo test, please contact us.

Fingertip Movement

ABREX®-A is specially designed for simulation of the human fingertip movements on the touchscreen product, for example, smart phone, pad, watch and other electronic wear. The common touch, zoom and fast double stroke swiping movements cause imperceptible abrasion on the touchscreen. Those unavoidable wear diminish the functionality of surface coatings.

Applications

ABREX®-A has two modes: standard ABREX® and an additional A mode. Within the standard mode, various tests including touch and zoom motions simulation can be performed. The additional A mode is designed to simulate the swipe movement which occurs often on the touchscreen, either during gaming or other situation.

Principle

ABREX® -ABRASION, is a soft-chemo-mechanical fingertip & hand abrasion and 99% simulation of the reality with the same wear pattern. It is a highly complex abrasion process which involves:

  • Firstly a 45° angle impact driven by a dynamic pneumatic cylinder attached with a viscoelastic fingertip under a defined load;

  • Then a friction rubbing or tumbling motion between the sample and a textile containing dirt, dandruff, oil, sweat or various types of testing liquids;

  • Followed by a retraction movement with or without the contact at the surface depending on the application.
