InvenSense Inc. has rolled out a sensor system-on-chip (SoC) platform aimed at being a total microelectromechanical systems (MEMS) solution for wellness/fitness-centric smartwatches and activity trackers. Called the ICM-30631, the SoC includes InvenSense’s 6-axis integrated MEMS motion device (that includes a 3-axis accelerometer and a 3-axis gyroscope), embedded ARM Cortex class processor and InvenSense’s digital motion processor (DMP) software blocks. The SoC can deliver lower power sensor processing in a small 3mm by 3mm 24-pin QFN package, the company says.
The IC can be used to deliver activity recognition, photoplethysmography (PPG) sensor-related measurements (such as motion artifact correction and heart rate variation), sleep quality analysis, calorie counter, speed/distance, floors climbed and recognize wrist worn gestures. InvenSense says the SoC is designed to speed up time to market for OEMs looking to create new and different smartwatches and other wearable devices.
According to Eitan Medina, VP of marketing and product management at InvenSense, it requires a great deal of engineering known-how to deliver activity recognition, heart rate monitoring, sleep analytics, floor count and speed/distance building blocks to a wrist-worn smart device. The ICM-30631 is simplifying the process and at a lower power than traditional methods, he says.
