발행일 : 2020년 07월 페이지 정보 : 영문 PDF > 80 Slides, Excel file > 4,350 Patents

Yole Developpement에 의하면 MEMS 센서 및 액추에이터 시장은 2019-2024년간 출하액으로 +8.3%, 출하대수로 +11.9%의 성장을 나타낼 것으로 예측되며, 가전제품 부문이 60% 이상의 점유율을 차지할 전망입니다. 2019년에 공개된 특허 건수는 다소 감소를 나타내고 있지만 관성 센서, 마이크로미러, 압력 센서 등의 부문은 안정적으로 추정되고, 자동차(헤드 램프, 헤드업 디스플레이 등)과 민생 용도(지문 센서, 음성 머신 인터페이스)에 특화한 압전 MEMS에 관해서는 강력한 특허 활동이 확인되고 있습니다. 또한 2019년은 중국 기업의 적극적인 특허 활동도 특징적이었습니다.

A stable IP landscape with new opportunities and increasing competition

MEMS sensors and actuators are key components in numerous applications. Indeed, electronic devices need to be more and more connected to the real world in order to provide better experiences to the customer. Sensing and interacting with the environment is therefore becoming critical, especially in the automotive, consumer and industrial markets. Indeed, autonomous vehicles, AR/VR and industry 4.0 require the use of numerous sensors to realize their dreams.

According to Yole Développement, the market will exhibit +8.3% growth in value and +11.9% growth in units, with consumer still having the greatest share (over 60%) from 2019 to 2024. This growth rate is below previous rates, however, and the automotive and consumer markets are levelling off. As growth slows down, competition between the different players is getting tougher and tougher, since the cake is not as big. On the M&A front, MEMS-related acquisitions declined during the last year, reflecting the weaker, general semiconductor-related M&As and a consolidation of the business. Furthermore, there were no significant new entrants, and existing players struggled to compete against one another.

In this context, this MEMS Sensors & Actuators 2019 Patenting Activity report aims to decipher the recent patenting activities and related R&D developments of MEMS players. This report also tracks weak signals in order to find new applications or new R&D directions that are currently being investigated, as well as newcomers entering the landscape.

The patents published in 2019 confirm the slight decrease that we can see at market level. Indeed, even if the number of patents remains quite significant, most of the IP segments have remained stable. This is the case for inertial sensors, micro mirrors or pressure sensors. However, despite this general trend, some recent developments of MEMS for new applications seem promising. For instance, patents in 2019 confirm the strong activity related to piezoelectric MEMS dedicated to automotive (headlamp, head-up display, etc.) or consumer applications (fingerprint sensors, voice machine interface).

2019 is also marked by the strong patenting activity of Chinese players. Indeed, Chinese players filed over 60% of the patents published in 2019 and even led most of the MEMS devices. This strong activity could be a sign of the significant investments that Chinese companies have made to boost their competitiveness and challenge major European and US companies.
