Latest Patents

One of Hsin-Tang Chien's latest patents is a multi-axis capacitive accelerometer. This innovative device features a first mass that is held by an anchor supported by a substrate. The first mass is asymmetrically suspended on the anchor using two cantilevers, allowing it to rotate about a rotation axis to sense acceleration in a direction perpendicular to the substrate. Additionally, a second mass is suspended within the first mass by a set of springs to detect acceleration in a direction parallel to the substrate. A third mass can also be included, suspended on the second mass by another set of springs to sense acceleration in a third direction. All three directions are mutually orthogonal, enhancing the device's sensing capabilities.

Another notable patent by Chien involves a multi-axis accelerometer that consists of a substrate with sensing electrodes and a structural layer. This structural layer includes anchor bases fixed on the substrate, with a first proof mass that has symmetric openings. The first proof mass is suspended over the substrate, and capacitors are formed between it and fixed sensing blocks on the substrate to sense acceleration along two in-plane directions. The second and third proof masses are asymmetrically suspended within the openings, forming differential capacitors for sensing out-of-plane acceleration.
