“…Table 1 summarizes several states of the art communication technologies used for implants. An implantable transceiver operating at 396 -447 MHz has been proposed in [4], in which a loop antenna is used for the transmission, the power consumption for a data rate of 25 kbps is 2.2 mW using OOK modulation for implant depth of 8 cm. Ultra-wideband (UWB) signaling in GHz band is considered as a low power approach because the active duty cycle in comparison to the bit duration is very low.…”

Wireless intra-body communication is a promising approach for providing efficient and secure connectivity for medical implants. The low power consumption of the electronics and the conductivity of the biological tissues facilitate the system implementation, which makes the technique more powerefficient than the traditional radio frequency wireless systems. The galvanic intra-body communication uses the electrical current for signal transmission in the conductive medium of the biological tissues. In this paper, we propose an ultra-low-power communication approach by implementing a galvanic impulse method for communication between an implant and an on-body device. The communication system is designed, manufactured with off-the-shelf electronic components, and measured in the phantom and in-vivo animal experiment. The implant power consumption is 45 µW for the data rate of 64 kbps with a bit error percentage below 0.5% for the implant depth of 14 cm. The design supports long-lasting battery-powered implant sensory and communication system.
