About Maistro Microelectronics (Nanjing)

Maistro Microelectronics, also known as MEMS Drive Inc., is a fabless semiconductor company focused on developing and manufacturing micro-electromechanical system (MEMS) actuators. The company was founded in 2014 by CEO Colin Kwan, who assembled a team with deep expertise in MEMS design, wafer processing, and packaging. Kwan, holding degrees in Electrical Engineering and an MBA, leveraged over two decades of experience in promoting advanced semiconductor and materials solutions in Asia's electronics industry to establish the company. Before founding MEMS Drive, he was instrumental in commercializing the first lens-based MEMS autofocus camera module with OPPO during his tenure at DigitalOptics (DOC).

The company operates on a fabless business model, concentrating on the design and marketing of its MEMS products while outsourcing the manufacturing process. This strategic approach allows for a focus on research and development, which is evident from its extensive patent portfolio in MEMS technology. MEMS Drive primarily serves manufacturers of portable electronics, with a significant focus on the smartphone camera market. A key milestone was a partnership with smartphone manufacturer OPPO, which utilized MEMS Drive's technology in its SmartSensor for smartphone cameras, demonstrated at the Mobile World Congress. The company has secured significant funding, including an $11 million Series B round led by Walden International, to ramp up production of its MEMS optical image stabilization (OIS) actuators.

MEMS Drive's core product is a MEMS-based actuator designed for optical image stabilization in mobile and automotive cameras. Unlike traditional voice coil motor (VCM) OIS systems that move the lens, MEMS Drive's product moves the much lighter image sensor. This method provides stabilization on five axes, counteracting shakes that can cause image blur. The actuator, which sits under the image sensor, can move it with sub-micron precision at high frequencies, achieving compensation within milliseconds. This results in clearer images, especially in low-light conditions, and consumes significantly less power than conventional VCM OIS systems. The company is also expanding into the automotive sector, adapting its technology for ADAS and autonomous vehicle cameras to improve image clarity and reliability in harsh environments.
