I. SmartMotion™: Precisely sensing every moment of motion, redefining device interaction

SmartMotion™ is a high-performance intelligent motion sensing solution developed by TDK's InvenSense. It focuses on the precise capture and analysis of motion posture and trajectory within three-dimensional space. Leveraging industry-leading MEMS inertial measurement unit (IMU) technology, MotionFusion™ sensor fusion algorithms, and edge intelligence processing capabilities. It overcomes the limitations of traditional motion sensors—such as insufficient accuracy, high power consumption, and weak interference resistance—to deliver high-precision, low-latency, and low-power motion sensing, serving as the ‘motor nerves’ of smart devices.

Core Technologies and Product Highlights

- Multi-axis integration, comprehensive performance: Features a 6-axis IMU covering 3-axis gyroscope and 3-axis accelerometer, alongside the 9-axis PositionSense™ solution integrating 6-axis IMU with 3-axis magnetometer, balancing fundamental motion detection with advanced posture positioning. Employs BalancedGyro™ technology to significantly enhance gyroscope stability, effectively suppressing vibration interference and ensuring detection accuracy in complex scenarios.

- Ultra-low power consumption, extended endurance: Optimised power design for battery-powered devices such as wearables, TWS, and AR/VR. Certain models deliver significantly lower power consumption than industry peers while maintaining high performance, enabling round-the-clock motion monitoring without frequent recharging.

- Edge intelligence, computational offloading: Incorporates an enhanced embedded digital motion processor (eDMP) supporting on-chip data fusion and motion recognition. This enables complex motion analysis without relying on the main processor, reducing system load and accelerating response times.

- Customised Adaptation, Comprehensive Scenario Coverage: Introducing customised IMU products like the ICM-456xx family, specially optimised for niche applications including TWS earbuds, smart glasses, smartwatches, and fitness trackers, balancing size, performance, and cost requirements.

Core Application Scenarios

Widely deployed in AR/VR headset posture tracking, smart wristband motion monitoring and health assessment, TWS spatial audio adaptation, drone attitude stabilisation, gaming controller motion sensing, and industrial equipment vibration monitoring. Enables seamless, precise interaction, empowering devices to intuitively understand user intent.

II. SmartSound™: High-Definition Audio Capture + Intelligent Noise Reduction, Unlocking Ultimate Audio Perception

SmartSound™ represents TDK's dedicated MEMS microphone solution for high-fidelity audio capture and intelligent sound perception. Leveraging core advantages including high signal-to-noise ratio, wide dynamic range, ultra-low power consumption, and acoustic activity detection (AAD), it overcomes traditional microphone limitations such as unclear audio capture in noisy environments and excessive continuous operating power consumption. This endows devices with ‘sensitive hearing’, enabling clear voice interaction and precise sound event detection.

Core Technologies and Product Highlights

- High-fidelity audio capture: Flagship MEMS microphones including the T5837, T5838, and T5848 models deliver a signal-to-noise ratio (SNR) of up to 68dBA and an acoustic overload point (AOP) of 133dB SPL. This combination ensures both the capture of faint sounds and robust distortion resistance in high-sound-pressure environments, enabling clear voice and critical audio signal acquisition even in noisy settings.

- Multi-mode power management: Supports seamless switching between high-performance mode, low-power always-on mode, ultrasonic mode, and sleep mode. Consumes merely 130μA in always-on mode and 330μA in high-performance mode, balancing audio quality with extended device battery life.

- Intelligent Acoustic Activity Detection (AAD): Autonomously recognises specific sound events such as keyword speech, glass breakage, smoke alarms, and infant crying. Triggers system wake-up from sleep without requiring continuous full-power operation, significantly reducing standby power consumption for edge AI and IoT devices while extending battery life.

- Extensive Interface Compatibility: Supports multiple digital interfaces including PDM and I²S, enabling direct integration with various SoCs, MCUs, and IoT processors. Plug-and-play functionality simplifies hardware development while accommodating multi-platform device integration requirements.

Core Application Scenarios

Deeply optimised for scenarios including:

- Call noise reduction and voice wake-up in TWS earbuds

- Voice interaction in smart speakers

- Voice control in AR/VR glasses

- Sound monitoring in smart home security systems

- High-definition audio capture in action cameras

- Voice command input via TV remote controls

Delivering clear, uninterrupted audio perception for seamless, efficient voice interaction.

III. SmartPositioning™: All-Scenario Precision Positioning, Eliminating Blind Spots

SmartPositioning™ is TDK's high-precision, high-reliability intelligent positioning solution. It integrates inertial navigation, tunnel magnetoresistance (TMR) sensing, GNSS, Wi-Fi/BLE wireless technology, and multi-source data fusion algorithms. It resolves positioning failures in scenarios with weak satellite signals—such as indoors, tunnels, and urban canyons—achieving all-scenario, all-weather, continuous, and stable precision positioning and attitude tracking. This endows devices with an ‘accurate sense of direction’.

Core Technologies and Product Highlights

- Multi-technology fusion for blind-spot-free positioning: Leveraging the 9-axis PositionSense™ core hardware (SmartMotion™ 6-axis IMU + TMR 3-axis magnetometer), combined with software algorithms like Pedestrian Dead Reckoning (PDR) and Inertial Navigation (INS), alongside wireless technologies such as GNSS, Wi-Fi, and BLE. Enables seamless indoor-outdoor transition and sustained precise positioning even without satellite signals.

- High-Precision Interference Resistance: Employs a dual-chip separated design to mitigate stress, magnetic field, and thermal interference inherent in single-chip integration, enhancing positioning stability. Supports rapid automatic calibration to maintain positioning accuracy during prolonged operation, meeting centimetre-to-decimetre level positioning requirements.

- Scenario-Specific Positioning Suites: Offers specialised suites including VENUE indoor positioning, AUTO vehicle/robot autonomous positioning, TRACK vehicle trajectory estimation, and DRIVE ADAS precision positioning. Each suite is optimised for distinct scenarios to accommodate diverse positioning requirements.

- High Reliability and Safety: Features positioning data integrity monitoring, hot restart after power loss, and RTK compatibility. Maintains stable positioning output even under extreme conditions or brief sensor failures, making it suitable for safety-critical applications in automotive and industrial sectors.

Core Application Scenarios

Widely deployed across automotive ADAS driver assistance, micro-mobility fleet management, industrial robot navigation, drone precision hovering, indoor/outdoor wearable navigation, AR/VR spatial positioning, and indoor guidance systems for shopping centres/hospitals. This comprehensively resolves positioning dead zones, ensuring precise and controllable device operation.
