In this paper, we present the properties of a communication channel used for implantable devices. The human-body communication (HBC) channel was proposed for data communication in implantable devices. The impulse response was measured using a channel-mimicking model, which mimics electrical losses caused by human body tissues. Furthermore, we compared two types of channel-mimicking models to evaluate their applicability depending on the measurement environment. The resultant impulse responses of the HBC channel showed that HBC does not cause severe changes in the channel properties even when the implantable device is rotated.
在本文中,我们介绍了用于植入式设备的通信信道的特性。人体通信 (HBC) 信道被提议用于植入式设备中的数据通信。使用模拟人体组织引起的电损耗的信道模拟模型来测量脉冲响应。此外,我们比较了两种类型的信道模拟模型,以根据测量环境评估它们的适用性。HBC 信道的脉冲响应结果表明,即使植入式设备旋转,HBC 也不会导致信道特性发生严重变化。
