Our Story
Today, manufacturers and DIY project makers who want to develop applications for improving human health and monitoring face the challenge of sourcing expensive, complex sensors or developing their own from scratch. This high cost and technical complexity create significant barriers, limiting innovation and accessibility in health monitoring applications.
This is unacceptable because it restricts the potential for widespread advancement in health technologies that could benefit many.
We envision a world where vital sign sensors are not only affordable and easy to use but also powered by advanced signal processing and AI. These technologies enable vital signs to be detected with minimal effort required from users, allowing for seamless integration into various health monitoring applications.
To bring this vision to life, we are developing and providing high-quality, user-friendly, and affordable vital sign sensors. Our cloud-based solutions leverage the power of advanced signal processing and artificial intelligence, simplifying the process for manufacturers and DIY enthusiasts, and enabling widespread innovation in health monitoring.
Intelligent Cloud Platform
All the sensors we developed are powered by our cloud platform using advanced signal processing and AI.
Our sensor modules are:
LightSense
LightSense employs optical fibre sensor that utilizes advanced photonic technology to accurately detect heart rate and breath rate.
It is non-invasive, lightweight, and highly sensitive, making it ideal for continuous health monitoring in both clinical settings and personal health applications.
- By measuring the variations in light absorption and reflection through optical fibers placed on the skin, this sensor provides precise and real-time monitoring of vital signs.
Target product release: Q4 2024
WaveSense
WaveSense uses millimeter radar sensor that offers versatile functionality with its dual capabilities.
This sensor operates in the millimeter-wave spectrum, ensuring high accuracy and penetration through obstacles like clothing, providing reliable and non-contact vital signs monitoring.
- At long range, it can detect the presence of individuals or objects, making it suitable for security and monitoring applications.
- At short range, it excels in measuring heart rate and breath rate by detecting minute chest movements.
Target product release: Q1 2025 (Long range version)
SurfaceSense
SurfaceSense uses the Spoof Surface Plasmon technology that exploits the unique properties of surface plasmons to monitor vital signs through direct contact with a piece of cloth.
This innovative sensor is built as a cloth which is ideal for integration into wearable health devices, ensuring accurate and continuous health data with direct skin contact on the surface of the cloth.
- By embedding plasmonic structures in the sensor, it can detect subtle physiological signals such as heart rate and breath rate through fabric, offering a non-intrusive and comfortable monitoring experience.
Target product release: Q1/Q2 2025
WiFiSense
WiFiSense leverages existing WiFi signals to detect human presence and monitor breath rate.
By analyzing the disruptions and variations in WiFi signal patterns caused by human movement and respiration, this sensor can accurately determine if a person is present and track their breath rate.
This innovative approach utilizes machine learning algorithms to interpret the signal changes, providing a non-contact and unobtrusive solution for health monitoring and presence detection.
We are actively evaluating and refining this technology to ensure high accuracy and reliability for various applications, including smart home systems and health monitoring.
