Title: Narayanan Rajan: Innovator in MEMS Technology
Introduction
Narayanan Rajan is a prominent inventor based in Atlanta, GA, known for his contributions to micro-electromechanical systems (MEMS) technology. With a total of 2 patents, he has made significant advancements in the field, particularly in the development of innovative control systems and mirror technologies.
Latest Patents
Rajan's latest patents include groundbreaking work on MEMS micro mirrors driven by electrodes fabricated on another substrate. This invention involves an array of electrostatically tiltable mirrors formed in a MEMS structure. A first silicon-on-insulator (SOI) wafer is etched to create an array of tiltable plates, which are joined to the remainder of the wafer through pairs of torsion beams. A second SOI wafer is also etched to form cavities corresponding to these tiltable plates. The process culminates in the bonding of the two SOI wafers, followed by the removal of handle layers and dicing into chips, ultimately leading to the release of the tiltable mirror plates.
Another notable patent is the multiplexed analog control system for an electrostatic actuator array. This system is designed for a MEMS array of electrostatic actuators, such as tiltable mirrors in optical switches. Each actuator features a variable gap capacitor as part of its movable mechanical element. The system includes a hold capacitor connected to each actuator capacitor, with a selectable high-voltage inverter providing a bipolar drive signal. This innovative design enhances the performance and efficiency of MEMS devices.
