Title: Innovations of Chien-Shien Yeh
Introduction
Chien-Shien Yeh is a prominent inventor based in Tainan County, Taiwan. He has made significant contributions to the field of technology, holding a total of 10 patents. His work primarily focuses on mechanical encoders and scanning devices, showcasing his expertise in innovative engineering solutions.
Latest Patents
One of his latest inventions is a mechanical encoder that includes an assembly, a flexible element, and a signal sensing module. The assembly features a plurality of poking/stirring structures that provide a unique poking and stirring function. The flexible element consists of a first piezoelectric layer and a second piezoelectric layer, which are stacked together using an attach material. This design allows the poking/stirring structures to interact with the flexible element, generating an electrical signal in response to its deformation. The signal sensing module then processes this electrical signal to produce corresponding position and direction signals based on the movement of the poking structures.
Another notable invention is a two-dimensional scanning and reflecting device. This device comprises a vibration component and a scanning component. The vibration component has a free end, while the scanning component includes a frame body, a mass block, and a mirror. The frame body connects to the free end of the vibration component, and the natural frequency of the mirror corresponds to a specific frequency. The mass block is positioned eccentrically on the frame body, aligning with another frequency. When the vibration component receives a multi-frequency signal, the mirror vibrates in different axial directions, enabling advanced scanning capabilities.
