Summary of the Inventive Concept
An improved wearable heart activity sensor device with enhanced signal quality, improved skin contact, and optimized heart activity monitoring, providing more accurate and reliable physiological measurements.
Background and Problem Solved
The original patent, 'Wearable heart activity sensor device', has limitations in signal quality, skin contact, and heart activity monitoring. The new inventive concept addresses these limitations by introducing specific wavelength LEDs, textured substrates, and individual user calibration, thereby improving the overall performance and accuracy of the wearable heart activity sensor device.
Detailed Description of the Inventive Concept
The new inventive concept comprises a wearable heart activity sensor device with a substrate of optically transparent material, at least one LED arranged on the substrate, and a processing unit configured to analyze data from the sensor device and provide real-time feedback to the user. The LED is configured to emit light at a specific wavelength to enhance signal quality. The substrate comprises a textured surface to improve skin contact and reduce motion artifacts. The device is calibrated based on individual user characteristics, and the device's sensitivity is adjusted to minimize false positives. Additionally, the at least one LED is arranged on a flexible arm to accommodate varying skin topographies and improve signal stability.
Novelty and Inventive Step
The new claims introduce the use of specific wavelength LEDs, textured substrates, and individual user calibration, which are not present in the original patent. These features provide a significant improvement in signal quality, skin contact, and heart activity monitoring, thereby constituting a non-obvious inventive step.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept could include using different types of light sources, varying the texture and material of the substrate, or incorporating additional sensors for multi-modal physiological measurements.
Potential Commercial Applications and Market
The enhanced wearable heart activity sensor device has significant commercial potential in the healthcare, fitness, and sports industries, where accurate and reliable physiological measurements are crucial for personalized health monitoring, athletic performance tracking, and medical research.
