The patent filed by Japan Display Inc. describes a wearable detection device that can be worn on a finger to measure biological information. The device includes electrodes, a light source, a light sensor, and a control circuit to measure this information. The light source emits various types of light, such as red, infrared, near-infrared, and green light, to interact with the finger, while the light sensor captures the response. The device can calculate pulse wave velocity, blood pressure information, and pulse frequency based on the data collected, and can transmit this information to other devices using a communication circuit.
Additionally, the device incorporates features like insulating parts to prevent interference from adjacent fingers, a temperature sensor to adjust data transmission based on temperature changes, an acceleration sensor to account for movement, and a coil for charging the battery using a magnetic field. The design also includes specific configurations for the electrodes, openings for light transmission, and the placement of components to optimize functionality. These features collectively enhance the accuracy and usability of the wearable device for monitoring and analyzing various biological parameters in real-time.
