Sound Energy Harvest

Sound Energy Harvest is a practice that converts sounds into electrical energy for the digital/analogue application. This is possible through different technologies, e.g. electromagnetic induction or Piezoelectric fibres. Applying a Dickson multiplier circuit, it's possible to transform your musical instrument in a energy generator and harvest a small amount of energy if it attends the necessary conditions:

  1. Your instrument can play louder than 80 dBs

  2. It can play a frequency note equivalent to the resonance frequency of your pickup mic

This application has not been stimulated that much due its results on a quantitative scale, such as solar or wind energy. However, new technologies and studies have been proving that it can be a solution to increase the efficiency of your predictive maintenance and condition monitoring systems by eliminating the need for batteries and cables, expensive power sources that should be a part of the past. Besides its dependency from long distance connections to renewable energy sources and suppliers.

The intention of this research isn’t only to stimulate this digital practice but also to experiment its concept of renewable energy sources as an artistic investigation and experience for its participants. The promotion of renewable energy in an artistic practice isn't only solving ambiental problems, but it also has the potential to integrate a community, allowing an active participation into their mutual / ethical problems. Besides transforming its art into an action of conscientization through culture and science. The project also counts with the direct participation of the audience into the music composition through a web platform and the production of artworks with this material.

The coming pictures were the first experiment in 2018 that I realized with my cello. I used a circle of standard piezos as the receiver connected to a dikson multiplier and a capacitor.

This research is going to be back to activites in 2022 together with Adam Pultz Melbye and electonic engineer.
