Our Product
Our solution is a biomechanical energy harvesting technique using a new generation of piezoelectric materials which convert mechanical energy into electrical energy. One of the most obvious examples of energy harvesting are solar panels. They allow us to scavenge power from an ambient heat and light sources. In the same way our method exploits the piezoelectric effect of some materials (crystals, ceramics and polymer films) which produce electricity when subjected to mechanical stress, pressure, or other external force. For wearable devices the most common energy source are body movements: the arms and legs when walking, the chest during breathing, and even the beating of the heart. A single breath, for example, generates about a watt of power (0.82). When you walk across a room, each step can produce about 70 watts worth. To put this into perspective, a cardiac pacemaker only needs 50 microwatts to work for 7 years
This composite allows for:
Superior energy harvesting performance,
long-term mechanical stability,
and increased piezoelectric output voltage.
Spincasting allows for accelerated conductivity through increased surface area. Since our piezoelectric composite is based on PDVF and carbon-based nanoparticles it is easy to produce and easy to scale. In summary, we have a multilayered composite film that creates and stores current generated from walking, breathing or movement for an excellent performance output. The piezoelectric composite is a top and bottom layer of electrodes, made of silver nanowires, spin coated on top of the PVDF nanofibers and encased in a layer of silver.
