Latest Patents

Among Guanghua Wu's most recent innovations is the process of fabricating capacitive microphones featuring movable composite conductors and stationary single conductors. This invention outlines a method for creating a MEMS microphone that utilizes two capacitors. The first capacitor's signal output is designed to be the additive inverse of the second capacitor's output, allowing the total signal output to reflect the difference between the two. Importantly, in at least one of these capacitors, a movable or deflectable diaphragm operates laterally relative to the fixed capacitor plate, avoiding traditional issues such as squeeze film damping and noise, thus significantly enhancing microphone performance.

Additionally, he has developed another process for fabricating capacitive microphones that incorporate a movable single conductor paired with a stationary composite conductor. Similar to his previous invention, this design leverages two capacitors and delivers improved signal quality by ensuring that unwanted noises and damping effects are minimized.
