- What enhancements does it offer versus SmartBug 1.0?
- Its potential applications.
TDK recently announced the InvenSense SmartBug 2.0, designed for consumer and IoT applications. The remote data-collection module brings with it many new features over the previous model.
“SmartBug 2.0 will take digital transformation to the next level by not only being a trusted source of smart sensor data, but by providing the ability to create efficient machine-learning models on a 2.5- × 3-mm sensor,” said Sahil Choudhary, Product Marketing Director at InvenSense.
The SmartBug 2.0 packs an ICM-456xy inertial measurement unit (IMU) loaded with various sensors, including an accelerometer, gyroscope, magnetometer, pressure sensor, temperature sensor, humidity sensor, and ultrasonic time-of-flight (ToF) sensor. Moreover, the IMU is equipped with machine-learning (ML) capabilities, allowing users to build, test, and deploy ML models on the IMU itself.
Considering that SmartBug 2.0 provides a head-tracking solution designed for TWS and augmented-reality glasses, users can create their own algorithm classifications, such as an exercise classification for tracking squats, pushups, and jumping jacks. It can also be used to create gesture classifications, including those for fight, clench, shake and more.
On top of that, the platform’s compact and wireless design makes it easy for users to test ML models in real use cases, alter the parameters accordingly, and even create models with the lowest power.
The SmartBug 2.0 makes use of TDK’s VibeSense360 head-tracking solution, enabling TWS and audio companies to collect raw sensor and head-tracking data at the lowest power (280 µA at 50 Hz). Thus, it’s easy to learn and incorporate spatial audio.
That said, the latest platform retains some of the interface features from the original SmartBug, including Bluetooth LE, Wi-Fi, USB, and SD card logging, as well as previous applications such as asset monitoring, smart door lock, and sensor fusion. Ultimately, the SmartBug 2.0 provides an easy-to-use prototyping experience, allowing OEMs to garner insight, signatures, and environmental variations.
