Optical Sensing System for Determining Body Water Content - A simplified explanation of the abstract
This abstract first appeared for US patent application 18593532 titled 'Optical Sensing System for Determining Body Water Content
The patent application describes an electronic device with detectors that measure light emitted towards a user to determine water content in the user's tissue.
- Electronic device with detectors measuring emitted light from tissue
- Processor calculates decay constant of emitted light
- Water content metric of user determined using decay constant
Potential Applications: - Health monitoring devices - Fitness trackers - Medical diagnostic tools
Problems Solved: - Non-invasive measurement of water content in tissue - Real-time health monitoring
Benefits: - Improved health tracking - Early detection of dehydration - Enhanced medical diagnostics
Commercial Applications: Title: "Advanced Health Monitoring Devices for Personal Use" This technology can be used in wearable health devices for consumers, medical equipment for professionals, and fitness trackers for athletes.
Questions about the Technology: 1. How does this technology improve upon traditional methods of measuring water content in tissue?
- This technology offers a non-invasive and real-time solution, unlike traditional methods that may require invasive procedures or lab tests.
2. What are the potential limitations of using light emission to measure water content in tissue?
- Light emission may be affected by factors such as skin pigmentation or ambient light, which could impact the accuracy of the measurements.
Original Abstract Submitted
Embodiments are directed to an electronic device that includes a housing, a light emitter, a first detector positioned at a first separation distance from the light emitter, and a second detector positioned at a second separation distance from the light emitter. The electronic device can include a processor that is configured to cause the light emitter to emit light toward a user, receive a first measurement from the first detector based on a return of the emitted light from tissue of the user and receive a second measurement from the second detector based on a return of the emitted light from the tissue of the user. The processor can determine a decay constant of the emitted light using the first measurements and the second measurements, and determine a water content metric of the user using the determined decay constant.
