Wireless Telemetry Sensor System

Smart overview of the Invention

The Wireless Telemetry Sensor System is a multi-detector wearable medical sensor that integrates various measurement capabilities into a single device. It combines biopotential, optical, temperature, acceleration, and acoustic measurements to monitor vital signs and physiological waveforms. By leveraging sensor fusion and deep learning algorithms, it can provide early warnings of medical complications. The system is designed to be adaptable, with an expansion port and accessory cables allowing for flexible configurations, including continuous electrocardiogram (ECG) measurements, fetal ECG, and electroencephalogram (EEG).

Technical Specifications

The sensor is equipped with multiple communication technologies, including Bluetooth Low Energy (BLE), Wi-Fi, 5G LTE-M, Near Field Communication (NFC), and Ultra Wideband (UWB) radios. It can also charge and communicate via USB. The processing system within the sensor is capable of collecting, analyzing, and wirelessly transmitting physiological data. This enhances its utility in both hospital and home settings, offering comprehensive patient monitoring without the bulkiness of traditional systems.

Functional Capabilities

Designed for versatility, the sensor can measure a range of physiological parameters. It can collect synchronized ECG, bio-impedance, and photoplethysmography (PPG) data to calculate heart rate, respiration rate, and temperature. Additionally, it estimates blood pressure using pulse arrival time and measures oxygen saturation continuously. The sensor includes thermistors for temperature estimation, a motion sensor for detecting movement and seismocardiography, and a MEMS microphone for heart and lung sounds.

Advanced Features

The sensor incorporates a Bluetooth radio module for connectivity with mobile gateway devices, allowing data transmission to hospital monitoring tools. It also features a haptic interface for generating tactile responses. The processing system, equipped with a microcontroller, processes and transmits raw data to a gateway device, facilitating real-time monitoring and alerting. The onboard Wi-Fi module supports direct communication with hospital networks, enhancing its integration into existing medical infrastructure.

Applications and Embodiments

The sensor's design supports various embodiments, including a low-noise, multi-lead analog front end for clinical-grade ECG measurements. It can adapt to different patient needs, such as monitoring fetal ECG or EEG. The system's Bluetooth and Wi-Fi capabilities allow for flexible deployment in hospital and transport settings, ensuring continuous patient monitoring. Additionally, the sensor's haptic interface provides multiple feedback options, enhancing user interaction and alerting capabilities.
