In the design of electronics, power is one of the most difficult restrictions to overcome, and current trends indicate this will continue to be an issue in the future. Power generation from the user can alleviate these restrictions and may allow the development of new efficient products.

The passive powering of electronic devices takes places when the user doesnt have to do any task different to the normal tasks associated with the product. The energy is harvested from the users everyday actions. Power may be harvested passively from body heat, arm motion, typing, walking or actively through user actions such as winding or pedaling.

DOORMATE has been designed to convert the mechanical energy supplied by the user in the act of cleaning the feet, into electrical energy to be used to ring the doorbell.

Another important innovation in this concept is the use of an efficient sound system, which uses the wooden door as a natural sound amplifier. Therefore, less energy will be necessary for the operation of the device.
