Fingertip Movement
ABREX®-A is specially designed for simulation of the human fingertip movements on touchscreen products, 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. This unavoidable wear diminishes the functionality of surface coatings.

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.

ABREX® -ABRASION, is a soft-chemo-mechanical fingertip & hand abrasion tester. The simulated wear pattern matches reality with 99% accuracy. It is a highly complex abrasion process which involves:
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.
VDE SPEC 90017 V1.0 – Durability and functionality testing of displays or surfaces, materials or products in the vicinity of the display.

Banknote Limpness Test
Limpness is referred as the banknote paper is less stiff due to the frequent handling
Normally correlates with soiling and structural deterioration, which results in a marded lack of stiffness
Specially designed adapter
Simulation the limpness abrasion between the banknotes and human hands
Teeth Abrasion Test
Specially designed adapter
Durability test of tooth replacement materials
Abrasion counterpart can be customized.
