Understanding Wearable IMUs
Wearable IMUs are compact, low-power, and highly integrated sensing modules specifically designed for wearable smart devices. They typically integrate MEMS gyroscopes, MEMS accelerometers, and often a magnetometer onto a single chip. These units incorporate low-power signal conditioning and data pre-processing algorithms, enabling real-time measurement and output of 3-axis angular velocity, 3-axis linear acceleration, and spatial magnetic field data related to human body movement and wearer posture. This provides core motion sensing data for wearable devices to achieve motion detection, posture recognition, health monitoring, and human-computer interaction functionalities.
Pricing Overview
The price of wearable IMU chips varies based on performance levels:
-
Basic 6-axis MEMS IMU chips for low-end fitness trackers range from $1.5 to $3.
-
Mainstream 6-axis models with low-power algorithms (e.g., Bosch BMI270, TDK ICM-42605), widely used in smartwatches, cost between $2.5 and $6.
-
High-end 9-axis IMU chips, which integrate magnetometers, are priced from $6 to $12. These are typically found in premium smart glasses and professional sports wearables that feature gesture control and high-precision motion tracking.
Industry Value Chain
The industry chain for wearable IMUs comprises three core layers:
-
Upstream: Key materials, including MEMS silicon wafers, SOI substrates, and ASIC circuits, are supplied by companies such as TSMC, GlobalFoundries, and Bosch, accounting for approximately 30% of the total cost.
-
Midstream: This layer is led by chip design (e.g., ADI, ST, TDK InvenSense), manufacturing (e.g., SMIC, Xintec), and packaging/testing (e.g., JCET Group). Core entry barriers exist in MEMS processes and low-power calibration algorithms.
-
Downstream: Wearable device manufacturers such as Apple, Samsung, and Xiaomi integrate IMU chips into modules, which are then incorporated into final products. Terminal demand dictates the requirements for chip performance, miniaturization, and power consumption, establishing a transmission logic of “technology upstream, demand downstream” across the entire supply chain.

Overview of Wearable IMUs
Wearable Inertial Measurement Units (IMUs) are devices that integrate sensors such as accelerometers and gyroscopes to measure the motion and orientation of objects. These units capture changes in motion in real-time and can calculate position and posture. When integrated into wearable devices, they are utilized in a variety of applications.
IMUs primarily include three types of sensors: accelerometers measure the acceleration of an object, detecting movements and vibrations influenced by gravity. Gyroscopes measure the angular velocity of an object’s rotation, helping to determine its orientation. Additionally, integrating a magnetometer allows for measuring direction based on the Earth’s magnetic field, thereby providing more precise positional information.
The applications of wearable IMUs are diverse. In sports and fitness, they are used to analyze athlete movements and measure the effectiveness of training. For example, during running or cycling, they can evaluate distance, speed, and exercise form in real-time. In rehabilitation, they serve as tools to monitor patient movement capabilities and track rehabilitation progress.
Furthermore, IMUs are widely adopted in devices such as smartphones and smartwatches. They contribute to features like automatic screen rotation, pedometers, and improved accuracy of location services. Particularly in augmented reality (AR) and virtual reality (VR) fields, IMUs are essential for precisely tracking user movements and enhancing immersion.
IMU-related technologies continue to evolve, with ongoing advancements in sensor miniaturization and precision. Recent IMUs offer higher accuracy data, and digital signal processing techniques enable noise reduction from measured data. The integration of AI for data analysis is also facilitating the identification of movement patterns and anomaly detection, which is expected to lead to the development of smarter fitness applications and medical devices.
Due to their convenience and multifunctionality, wearable IMUs are playing an increasingly vital role in daily life. New applications are likely to be explored to support health management and improve exercise habits. For instance, monitoring body movements during sleep could provide data to improve sleep quality.
Thus, wearable IMUs are powerful tools that capture, analyze, and encourage improvements in our daily movements. Continued technological advancements are expected to create new markets and services, making our lifestyles healthier and more convenient. IMU technology will continue to evolve and contribute to our lives through new applications.
