The system includes a high-precision, low-noise sensor that can detect minute vibrations (measured in microns) with no physical contact, and various software modules for comprehensive AI-based solutions for various applications.
R&D Background
Kyocera's new Millimeter-Wave Sensing System is capable of non-contact, high-precision detection of micron-scale vibrations using a millimeter-wave signal, making it possible to accurately detect human heartbeat and respiratory fluctuations, as well as minute vibrations of machines and buildings, wirelessly and remotely.
This system can be applied in many routine healthcare diagnostics, efficient physical health monitoring, and for detecting anomalies in manufacturing equipment - contributing to healthcare and fulfilling societal needs for a more labor-saving workplace.
Features
The system features low-loss millimeter-wave substrates made from Kyocera's proprietary materials, high-precision substrate manufacturing, and advanced statistical signal-processing technology developed for telecommunications equipment.
Contactless Detection of Minute Vibrations
Many systems that sense a person's heartbeat or breathing require physical contact, which limits potential applications. To accurately detect minute vibrations with a contactless intelligent millimeter-wave sensor, a main technical challenge has involved improving the sensor's signal-to-noise ratio.
Kyocera solved these problems by combining its original materials and signal processing technologies.
Accurate Heartbeat Interval Sensing
Contactless sensing systems for heartbeat and respiration using ordinary radio waves 1 and ultrasonic waves have been unable to deliver highly accurate (high time resolution) data that can be applied to psychoemotional monitoring and other applications. Kyocera's system enables more accurate measurement of heart rate variability because it can detect chest vibrations caused by a person's heartbeat with high accuracy. In addition to daily healthcare measurement, this technique can also be applied to stress analysis, autonomic analysis, and other applications.
AI Solutions and Software Modules for a Variety of Applications
The system's high-precision vibration detection capability not only detects and extracts human heartbeat and breathing, but also2 motion detection from building vibrations and manufacturing equipment in factories.
Kyocera is also proceeding with R&D into AI technologies that analyze and utilize millimeter-wave sensor data, and aims to provide solutions for a wide variety of applications by combining these technologies with various software modules (add-ons).
