Design and Implementation of a Low-Power Transmitter for Medical Applications
Abstract
Wireless sensor networks (WSNs) have become increasingly important in biomedical applications, where the FCC allocates the MICS bandwidth specifically for medical sensor devices. These networks enable sensor nodes to collect vital signals such as ECG, EEG, EMG, blood pressure, body temperature, and heart rate and transmit the data to a base station for storage, processing, and monitoring. The widespread adoption of Radio Frequency (RF) communications has significantly influenced modern healthcare technologies, encouraging research and investment from academia and industry. RF-based systems provide the advantage of wireless data transfer, which reduces wiring complexity and enhances flexibility in medical devices. For reliable communication, both transmitters and receivers must comply with specific operational parameters to minimize interference and ensure accurate data transmission. This study focuses on the design of a low-power transmitter for medical sensor applications, emphasizing efficient bandwidth usage, minimal energy consumption, and compatibility with sensor nodes. The proposed design aims to improve the performance of wireless medical monitoring systems and facilitate real-time data collection and analysis.
