Haptic sensations at Techtextil North America 2021

Simulating the corpuscles of the human hand.

Emtec will provide live demonstrations of its TSA tactile sensation analyser at the 2021 Techtextil North America in Raleigh, North Carolina, from August 23-25.

The TSA provides an objective measurement of the haptic characteristics of a fabric. The measurement of softness, roughness and stiffness and the calculation of the hand feel value are carried out quickly and reliably and the device can be used in research and development, quality assurance and product optimisation.

“When you’re a manufacturer coming up with new fabrics or new materials, you often need very specialised testing equipment to measure different parameters and you want results that are as objective as possible,” explains emtec global marketing and business manager Alexander Gruener. “For measuring parameters like tactile sensation – such as how soft and smooth something feels – it’s a bit trickier without the right equipment. This has traditionally meant using hand-panels, which are time-consuming and often highly subjective.”

Using a sound spectrum analysis and tiny rotating paddles, the TSA bypasses these challenges by simulating the corpuscles of the human hand that are responsible for haptic sensation – softness, smoothness and stiffness.

At the event, emtec representatives will demonstrate how the unique design of the TSA device enables it to differentiate between the three different parameters and arrive at a numeric value for a sample’s hand-feel. In addition, the they will illustrate current applications for use in production, including R&D, process and product optimisation, quality assurance, troubleshooting and benchmarking.
