Delivers Accurate Heart Rate Measurement (HRM)
While Walking, Running, Biking, and Gym Activities
InvenSense, Inc. (NYSE:INVN), the leading provider of
intelligent sensor system on chip (SoC) for Motion and Sound,
announced its motion artifact correction and heart rate variation
platform solutions for Photoplethysmography (PPG) sensors. PPG
technology consists of light-emitting diodes (LEDs) and
photodetectors to monitor pulse rate noninvasively. InvenSense’s
HRM sensor system solutions enable in-activity and continuous heart
rate monitoring by removing the motion artifact signal from the PPG
signal using its 6-axis integrated MEMS (3-axis accelerometer +
3-axis gyroscope) device to deliver accurate heart rate
(beats-per-minute) monitoring during elevated motion activities.
The HRM system solution also measures the R-R interval (the
interval from the onset of one R wave to the onset of the next one,
during one complete cardiac cycle) while static. This is used to
calculate Heart Rate Variability (HRV), a new biometric that
wearable devices are now providing their users to help determine
overall wellness and stress level.
PPG sensors for heart rate monitoring are fast becoming a
standard sensor in mid-to-high-end wearable devices like smart
watches, activity monitors, and Bluetooth headsets. Yet, the
limitation with many of today’s smart watches and activity trackers
using PPG sensors is that they either require the user to be very
still before initiating a heart rate measurement manually, or they
deliver inaccurate heart rate information while the user is in
motion. Ideally, heart rate measurement should be continuously
occurring without user intervention. InvenSense’s HRM solutions are
capable of delivering a typical heart rate (bpm) accuracy of +/6
bpm regardless of activity and an R-R interval of less than 10%.
InvenSense vital sign monitoring solutions are delivered as part of
InvenSense’s FireFly SoC wearable system platform that integrates
6-axis motion sensor, M0 core, and Digital Motion Processor (DMP)
blocks for efficient lower power processing and work in conjunction
with many of the leading PPG sensors.
“Delivering an accurate heart rate is vital to wrist-worn
wearable devices regardless of the activity in progress,” said
Eitan Medina, vice president of marketing and product management at
InvenSense. “Continuous heart rate monitoring will enable our OEM
partners and developers to correlate heart rate and stress level to
activity, context, and even meeting/calendar events, thus helping
them deliver valuable wellness/fitness-related services to their
end users. Accurate vital sign monitoring is imperative for the
wearable market to help drive mass market adoption. As
wellness/fitness services become more useful and intimate because
of vital monitoring data, better life style choices can be made.
InvenSense will continue developing sensor SoC solutions to assist
our wearable customers achieve their goals of accurate and
dependable health/fitness data.”
