Siores describes how the hybrid fibre is made up of two parts. The core is made out of piezoelectric material, which comes from the Greek word, meaning applying pressure. When pressure is applied, or the material is vibrated, the vibrations are converted into voltage that can be stored as energy in a rechargeable battery or used immediately. The outer coatings are an organic photovoltaic material. The core is made from of polymer material, avoiding the more efficient but lead-containing ceramic material, and the production costs are low. Also, as they are in a fibre format they can be made in different diameters, and can be weaved, knitted and processed like any other fibre into textile structures.
Siores is excited about the possibilities, ‘the fibre can be used for wearable applications, for charging mobiles while on the move. For more power hungry applications, these fibres can be chopped into a needle size. For example, a pine tree structure, made with these hybrid fibres. The tree structure does not have to track the sun, the sun goes around the tree and harnesses enough energy for the home from sun wind and rain.’
