Wiper Application |
|
Designing a windshield wiper system that effectively cleans a windshield is not an easy task given the
constraints. The combination of different blade lengths, durometeres, low and uneven pressures, and varying
windshield contours combine to make this a complicated material and dynamics problem. Knowing the force
distribution between the windshield and the blade at various positons along blade length provides key
insight into how to improve performance.

Tekscan developed a 0.1 mm high, flexible polyester sensor strip containing 100 individual force sensors arrayed
along it’s length. The accompanying electronics, calibration fixtures and software are sensitive, flexible and
portable enough to measure the windshield to wiper blade interface profile under various conditions. |
