Application: Human Interface
For the first time ever it's now possible to measure shear forces directly at the interface point of two mating surfaces. Our shear sensor is an ideal research
tool for human body interfaces of clothing, shoes, gloves, backpacks or any object that comes in contact with the human skin and creates shear forces.
Tactilus® reveals the vector of the shearing action in real time. Tactilus® is a valuable aid in human factors engineering and ergonomics, in both research as well as a clinical assessment tool.
"Until now there has not existed a method to measure actual contact shear at the interface surface. Computer modeling with FEA software orother analysis tools yielded predictions. Now for the first time ever the engineer can place a sensor at the interface surface and collect shear data in real time!" ~ Jeffrey G. Stark, CEO
Tactilus technology
Tactilus® is a matrix based tactile surface sensor that works by the principle of piezoresistance. Each Tactilus® sensor iscarefully assembled to exacting tolerances and individually calibrated and serialized. The architectural philosophy of Tactilus® is modular allowing for portability, and easy expansion. Tactilus® employs
sophisticated mathematical algorithms that intelligently separate signal from noise, and advanced electronic shielding techniques to maximize environmental immunity to noise, temperature and humidity.
System includes
- Shear sensor element
- Electronic controller
- Software and cables
