This invention is a low-cost, low-power wireless system designed to monitor vital health signs like heart activity (ECG) and blood oxygen levels (SpO2) remotely. It uses advanced technology to send health data from a wearable transmitter to a nearby receiver, which then sends the information to a mobile device like a phone or tablet. This system is reliable and easy to use, making it ideal for early detection of serious health issues, especially in areas with limited access to healthcare.

The growing prevalence of cardiovascular diseases (CVDs) and respiratory illnesses, particularly in low and middle-income countries, underscores the necessity for early and accessible diagnostic tools. Traditional healthcare infrastructures often fall short in providing timely and cost-effective diagnostics, leading to preventable fatalities. The advent of advanced wireless communication, sensor technologies, and integrated circuits offers a viable solution for remote health monitoring. By establishing a robust communication system within the Med Radio spectrum band, this invention enables continuous, non-invasive monitoring of vital health parameters like ECG and SpO2 levels. This approach not only facilitates early detection and management of life-threatening conditions but also extends healthcare reach, allowing a single specialist to monitor multiple patients simultaneously, thus addressing critical gaps in current healthcare delivery systems.
- Incorporates an injection inverter between a three-stage and a nine-stage ring oscillator for enhanced signal processing.
- Utilizes an edge combiner with symmetric gates to maintain a stable duty cycle for the transmitter output.
- Features a receiver with a Local Oscillator (LO) and programmable demodulator for flexible signal reception.
- Establishes a reliable wireless communication link in the MedRadio Spectrum band, ensuring minimal power consumption.
- Achieves low power and low cost, making the system suitable for widespread use in medical applications.
Wireless link has been successfully tested for ECG and SpO2 under actual operating conditions with the fabricated transmitter and receiver packaged test chips.
