Application: Sensor reliability detection and power management (Patent ID: US20240090800A1)
The patent filed by STMicroelectronics NV describes a wearable electronic device, such as a watch, equipped with optical sensors that can detect the level of contact between the user's skin and the sensors using electrostatic charge variation measurements. Based on this information, a contact reliability index (CRI) is generated to adjust the operation of the optical sensors, ensuring accurate measurements. The device includes components like ground and receiving electrodes, an electrostatic charge sensor, and a processor to determine the accuracy of measurements and generate the reliability index.
The device's processor can adjust the operation of the optical sensor based on the reliability index, ensuring that measurements are reliable, moderately reliable, or unreliable depending on the level of electrostatic charge variation detected. The device can also filter out frequencies from the measured electrostatic charge variation to improve accuracy. Additionally, the patent covers a method for generating measurements, determining reliability based on electrostatic charge variation, and adjusting sensor operation accordingly. The device is designed to be worn on the user's skin, ensuring physical contact between the optical sensors and the user for accurate readings, making it suitable for applications like heart rate or oxygen monitoring in wearable devices like electronic watches.
