Wiper-to-Windshield Force Measurement System

Windshield Wiper Pressure Mapping

Utilizing a tactile pressure sensor, the Wiper™ System measures wiper blade to windshield interface force profiles under various testing conditions. The Wiper system measures the force distribution along the entire length of the blade at different positions on the windshield, providing important insights to improve design. It is used as a research and development tool to improve blade and wiper system performance under different conditions such as “lift-off.”

Key Features & Benefits

System:

• Map force distribution along wiper blade

• Access real time or recorded data

• Dynamic measurement for “lift-off” testing

• Collects and consolidates static measurements at different angles to capture full wiper cycle

• Graphic and analysis capabilities

Sensor:

• Minimally intrusive, flexible, thin-film sensors

• Sensors specifically designed for use with wiper blades

• Sensors are durable and reusable

• Thin & incompressible sensors – dimensional stability is key for repeatable measurements
