Abstract-In this we use a piezoelectric crystal which gives variable voltage output depending upon the vibrations given on the crystal surface. This voltage is converted to current using suitable converter. Now the current is passed through a memristor‚ which has a corresponding resistance value. Whenever the current increases‚ the resistance value increases and the change in resistance is detected using a microwave generator connected at the end. Using the microwave level‚ an external device (similar

Liquid Crystal Display A liquid crystal display (LCD) is a flat panel display‚ electronic visual display‚ or video display that uses the light modulating properties of liquid crystals. Liquid crystals do not emit light directly. LCDs are available to display arbitrary images (as in a general-purpose computer display) or fixed images which can be displayed or hidden‚ such as preset words‚ digits‚ and 7-segment displays as in a digital clock.
