MICROSTAMP
The project MICROSTAMP was a 2023 winner of the PREMATURATION call for projects, led by the Innovation Lab of IP Paris.
THE PROBLEM ADDRESSED
Pattern application by stamps on material surfaces for strain measurements by image analysis for mechanical testing
Speckles made with spray paint are user dependent, difficult to control and to reproduce
Control the pattern according to the test and structure
The team has an expertise in characterizing and modeling the mechanical behavior of materials
TECHNOLOGY
Soft material stamps with designed patterns
Silicone-based stamps
CAD-aided design for application tools
Applied patterns used for digital image correlation or marks tracking techniques for strain field measurements
COMPETITIVE ADVANTAGES
Control pattern design by size, shape, and density
Pattern with a diameter as small as 180 microns
Custom-size stamps with non necessarily flat surface with dimensions up to 200 mm x 105 mm
Easy, safe to apply for reproducible patterns
