Textiles integrated with electronics and long-range (LoRa) wireless technology are revolutionizing e-healthcare by enabling remote patient monitoring through wireless body area networks. This article presents a smart textile-based LoRa technology system for monitoring heart rate and predicting body temperature over both short and long distances. The system incorporates a LoRa module integrated with a smart textile, featuring sensors for photoplethysmography, electrocardiography, and body temperature monitoring. An embroidered monopole antenna seamlessly integrates into clothing, offering triple-band wideband operation at 433, 610, and 915燤Hz with minimal susceptibility to human body effects and structural deformations. The proposed wearable antenna, assessed through specific absorption rate analysis, exhibits minimal exposure to electromagnetic radiation, ensuring user safety. The smart textile LoRa-enabled healthcare application (STLHA) monitors the received signal strength indicator, heart rate, and temperature data. Experimental results demonstrate effective outdoor communication ranges of up to 250爉 at 915燤Hz and 350爉 at 433燤Hz, with indoor ranges of up to 50爉. The STLHA offers a wireless solution for wearable devices, which enhances their functionality and usability in e-healthcare applications.
