This paper presents the transmission of multiple biomedical signals through the body channel communication. Since body channel communication has advantages in terms of convenience, security, and power consumption over the wire and wireless communication on various applications. In this paper, the attached patch-type sensor measures electrocardiogram (ECG) and body temperature. The analog signals convert to high-frequency signals, and modulated signals transmitted through the body channel externally appear through body contact with the LCD. The ECG signal is measured using three electrodes nearby the heart. The body temperature signal measured by a thermistor. The patch is designed to be easily attached to the body and is suitable for skin. It allows stable measurement and transmission of biometric signals without restriction on movement.
