Abstract
The implementation of radio-frequency communication technologies in biomedical or healthcare applications involves multiple issues such as interference with precision medical instruments and human health hazard because of electromagnetic waves. A novel visible light communication technology for transmitting and monitoring biomedical data is presented. White beam light emitting diodes are used as optical information emitters for efficiently transmitting biomedical data such as patient information text and wavelike body sensor signals. ON/OFF keying modulation is used to modulate the data onto the visible light beam, and a high-speed p-i-n photo-detector is employed at the receiver. Experimental analysis of the data collected using this system demonstrates the effectiveness of the proposed method.
