Efficient Sensor Mat For Energy Harvesting And People Counting

Abstract

In past few years, increase in production of less power consuming electronic devices made our lives more comfortable. Although, energy consumed by these moveable electronic devices will increase, the idea of energy harvesting in human surroundings arise a new interest among us. In our project we proposed a sensor mat which can harvest ambient energy source into usable electrical energy. As it will be successful approach to make power through a sensor mat. This objective can be accomplished by placing piezoelectric materials inside the mat and it placed at entrance where it allows maximum people to go through it. Whenever, the person steps on the mat it will generate a signal in the form of potential difference. This amount of potential difference will be dependent on the force exerted by human footstep. After receiving the threshold signal a program will run which will count the person and his direction. This would allow us to generate appropriate amount of electricity as well as counting the number of people and their direction.
