摘要
PURPOSE: A nano power generating element using a piezoelectric material and a rain sensing wiper controller are provided to produce energy in a vehicle itself to use as the power energy of the vehicle by converting physical energy like raindrop and wind to electric energy with a piezoelectric material.;CONSTITUTION: A wiper controller comprises a piezoelectric element(10), an electric current sensing part(20), a comparator(30), and a wiper speed control part(40). The piezoelectric element is installed in a windshield of a vehicle to generate electric current. The electric current sensing part detects the amount of the electric current generating in the piezoelectric element. The comparator selects and outputs a specific signal by comparing a set value and the amount of the electric current detecting in the electric current sensing part. The wiper speed control part controls the speed of a wiper by comparing the set value and the value outputted from the comparator.;COPYRIGHT KIPO 2012
