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
