Title: Innovations of Walid Daoud
Introduction
Walid Daoud is a prominent inventor based in Hong Kong, CN. He has made significant contributions to the field of energy conversion, holding a total of 6 patents. His work focuses on developing innovative technologies that harness energy from various sources.
Latest Patents
One of his latest inventions is the Omnidirectional Omni-Frequency Wave Energy Converter (WEC). This device includes a housing, a stator fixed to the housing, a rotor movable to the stator, and an oscillating mass connected to the rotor. The oscillating mass is designed to oscillate due to tilting and horizontal movements of the housing. It is also adapted to rotate along with the rotor. The friction generated between the rotor and the stator during relative movement induces electricity. This WEC has been demonstrated to effectively absorb water-wave energy from all directions and convert kinetic energy into electrical energy through the R-TENG system under various simulated water wave motions.
Another notable patent is the Triboelectric Generator, Biomechanical Energy Harvester, and Method of Making Triboelectric Material. This triboelectric generator consists of a first triboelectric material providing a first surface, with a first electrode attached to it. A second triboelectric material provides a second surface that contacts the first surface, along with a second electrode attached to the second triboelectric material. The two triboelectric materials are distinct from each other, and the electrodes are arranged to be electrically connected via an electrical connection. The first triboelectric material comprises a polymer material and an organic semiconductor material arranged within it.
