Abstract

People normally put up their windshield wiper when their car is parked under the sun. As the windshield wiper is moved back and forth across the windshield surface, the dust particles are tending to scratch the windshield surface. In addition, the windshield is susceptible to the heat build-up which is brought about by the sunlight, especially in the hot summer. The windshield wiper blade is therefore vulnerable to deformation which is caused by the hot of the windshield. Lifting the wiper manually is not practical nowadays as people use technology to ease thier everyday life. There a lot of actuator that can be used in the automotive industry. In modern day technology people would use simple and less components devices to reduce cost and maintenance. By using shape memory alloys (SMA) as an actuator, windshield wiper can be lifted automatically. This new generation of actuator can be used as a simple mechanism that can reduce the space and noise. The design of the wiper lifter is developed and the performance are tested using 12V and 6V battery. Results show that the higher the voltage, the faster the actuation time. 12V batteries have the best actuation time.
