Latest Patents
One of Daren Chen's latest patents is titled "Ultrasonic electrospinning for the production of fine and ultrafine fibers." This invention employs the advantages of ultrasonic vibration in the electrospinning process. The fibers are produced from an ultrasonic nozzle that is exposed to an electric field established between the nozzle and a target object. The exemplary embodiments include electrospinning techniques that produce fine and ultrafine fibers in high throughput via multiple jetting of spun solutions and melts. The use of ultrasonic vibration, sometimes combined with heating, reduces the voltage required for spinning. Additionally, vibrating power delivered to the nozzle can generate gas bubbles through solvent cavitation in the spun solution, enhancing the multiple jetting process.
Another notable patent is the "Dual channel jetting apparatus for 2D/3D electrohydrodynamic (EHD) printing." This EHD jet printing apparatus includes a circulation system for the printing fluid, which minimizes or eliminates clogging in the nozzle. The exemplary nozzle comprises at least two ink channels—one for flow to a droplet emitting opening and another for flow away from it. This configuration allows for the circulation of ink, enabling effective transfer to a substrate using an EHD technique that involves voltage or current modulation.
