Latest Patents

Guojun Ma's latest patents include a method of manufacturing an in-plane metal microneedle array. This invention describes a high aspect ratio in-plane metal microneedle array, along with a manufacturing method and a clamping and inserting auxiliary device. The process involves cutting a large-size metal sheet into smaller sheets and utilizing a clamping tooling composed of upper and lower metal cover plates. The inner sides of these plates feature grooves where the metal sheets are placed and fastened by bolts. Wire cutting is then performed on the tooling and the metal sheets to create a plane metal microneedle array with multiple microneedle bodies. Additionally, an assembling and clamping device is provided to facilitate the insertion of the microneedle array into the skin.

Another patent focuses on the in-plane metal microneedle array and its manufacturing method. Similar to the previous invention, this method involves cutting a large metal sheet into smaller sheets and designing the geometry and size of the microneedle array. A CAD model is created, and wire paths are cut according to this model. The unprocessed parts on both sides of the microneedle substrate are then cut to obtain the final in-plane metal microneedle array.
