TAIPEI, Dec. 26,
2024 /PRNewswire/ -- Fabless chip firm MEMS Drive
Hong Kong Ltd manufactures cutting-edge MEMS actuators targeted at
mobile imaging in portable electronics. The company uses its
proprietary MEMS design and process to allow CMOS sensors to
achieve swift and precise 'SensorShift' and is the first
semiconductor company to implement 5-axis stabilization in mobile
cameras.
"With edge computing capabilities steadily advancing, MEMS Drive
utilizes precise movement matching algorithms and artificial
intelligence [AI] to derive multiple image-enhancing features
besides just stabilization, such as super-resolution and improving
identification capabilities," says Colin
Kwan, CEO and President of MEMS Drive during an interview
with EE Times Asia. "MEMS SensorShift-driven image sensors overturn
traditional voice coil motors [VCMs], and could be applied to
mobile phones, sports cameras, wearable tech, surveillance,
autonomous vehicles, robotic vision and other products, bringing
unlimited possibilities to the future of imaging systems."
It is for these reasons that the company won an Innovation Award
and Best Sensor of the Year award for its piezo technology-enabled
autofocus actuator and optical image stabilizer (OIS) actuator at
EE Awards Asia 2024. Now in its fourth year, EE Awards Asia
honors some of the best products, companies, and leaders making a
difference every day in Asia's
electronics industry.
The MEMS autofocus (AF) actuator is a piezoelectric
multi-morphic thin film actuator that can move at Z-axis and
tip-tilt directions to achieve a 3-axis compensation. The MEMS
devices are designed to be based on standard silicon fabrication
processes, thereby enabling good scalability and ease of handling,
testing, and packaging.
According to Colin, this sensor-based technology offers multiple
advantages. "It provides 3-axis image adjustments as compared to
1-axis counterparts on lens-based AF systems; it also moves three
times faster and 10 times more precise by detecting positions of
less than a pixel, compared to 3-5µm on lens-based AF," he
explains. "And finally, by not using a motor to move the lens
around, it consumes up to 50 times less power and avoids heating
problems that could affect the image's quality."
Meanwhile, its OIS, known as SensorShift, is said to be the
world's smallest MEMS OIS actuator. It provides a 5-axis OIS
solution to improve clarity and achieve stable and precise
image.
"All vibrations in pitch, yaw, roll, translational X, and
translational Y can be compensated with a single MEMS chip," says
Colin. "Due to its high precision and fast response in active
movement, we can achieve another application called super
resolution. By shifting the imager 1 pixel or half a pixel in
different directions, capturing the image at each position, and
then merging and processing those images, we can get a 4X or even
higher-resolution image."
Colin notes that compared to traditional lens-based OIS, MEMS
Drive's MEMS OIS is a sensor shift solution that provides superior
stabilization performance with multiple advantages, including a
10ms fast response, just 4mW of power consumption, sub-pixel
precision, and high image resolution in low light and video without
blur.
"Powered by our patented electrical conductive flexure [ECF]
technology, the MEMS Drive actuator provides consistent, durable
performance," says Colin. "With over 2.5 billion test cycles
completed in continuous operation, these innovations are crucial
for ensuring the highest standards in automotive applications and
safety."
MEMS Drive's technology is suitable for smartphones, automotive,
wearable technologies such as AR/VR camera systems, sports cameras,
smart city applications, and robotic vision.
In this video interview, Colin also talks about his outlook for
the semiconductor and electronics manufacturing industry over the
next year, upcoming challenges amid the increasingly complex
designs and architectures, and the new opportunities in the
market.
