Possesses experience and know-how in MEMS-based thermal imaging sensors
The market is expanding to include smart devices, smart buildings, and industrial fields.

Yuwoo Electronics (CEO Yonghee Han), a company specializing in uncooled infrared sensors, is a company specializing in infrared sensors based on MEMS technology.

MEMS technology is fundamental to the development and production of thermal imaging sensors. Yuwoo Electronics is the only company in Korea with over 15 years of experience and expertise in MEMS-based thermal imaging sensors.

The company supplies its products to a variety of sectors. Its main business areas include smart devices, smart building automation IoT, automotive, and industrial. Specifically, its target markets include smart devices such as camera modules, non-contact thermometers, wearable bands and glasses, and DIY (home, car, security) products, as well as smart building automation IoT applications such as human detection, energy conservation, intruder detection, and fire prevention.

In addition, it is also used in the automotive field for night vision, passenger recognition (+air conditioning), and pedestrian detection, and in the industrial field for preventing overheating of distribution panels, preventing gas leaks, and preventing defects in pipes.

Yuwoo Electronics' product competitiveness lies in its position as the only supplier of TIS (Temperature Imaging Sensor) sensor chips based on WLVP (Wafer Level Vacuum Packaging). WLVP is recognized as an essential technology for the consumer market, enabling miniaturization, mass production, and low cost. The company announced that it has established the first mass production system for thermal imaging sensors by applying WLVP technology, which was first developed and released globally in 2010.

The company added that the amorphous vanadium tungsten oxide (α-VWOx) used by the company not only exhibits TCR characteristics equivalent to vanadium oxide (VOx), a patented material of Honeywell (USA) used by most companies, but also has a simple manufacturing process and can use general-purpose equipment, which allows for cost savings.


▲A microbolometer is a physical sensor that detects changes in the electrical resistance of a sensing material due to infrared energy incident on its surface, and converts this change into an electrical signal. Vacuum packaging is essential to minimize heat loss from the surrounding air.


FLIR of the US and ULIS of France are leaders in the microbolometer-type WLVP TIS sensor market. FLIR supplies WLVP sensor packages, from modules to systems, while ULIS offers sensors only in ceramic-metal can packages. Yuwoo Electronics emphasized that its WLVP-based sensors are priced competitively (~$30) compared to those of foreign companies.

The company is currently developing an 8-inch wafer-based sensor ROIC, completing the sensor MEMS process, and setting up the WLVP process. Additionally, wafer-level imaging tests are currently in progress and wafer-level function tests have been completed.

“Our infrared and thermal imaging sensors will be widely used in IoT sensors, smart devices, and next-generation vision systems, which have bright future market prospects,” said Han Yong-hee, CEO of Yuwoo Electronics. “We will begin mass production next year after trial production this year, and aim to achieve sensor sales of over 100 billion won by 2020.”
