Currently, wireless body area networks (WBANs) are developing rapidly. Miniature wearable devices which are light weight and low power consumption can be developed using modern technology. However, the WBANs research challenge is power consumption. This paper provides the two intrabody communication (IBC) methods review. The equivalent body channel models and modeling methods are analyzed. The conventional IBC WBANs architecture is reviewed and novel energy-efficient architecture and an IBC WBANs data transmission technique are proposed. The experiment was conducted in order to measure the BodyCom mobile module output power. The comparative analysis showed that the power consumption of the IBC proposed technique is 7 times lower than Bluetooth LE, and 14 times lower than ZigBee. The proposed technique can be applied in areas such as home and industrial automation, medical appliances, wearable devices, security, and internet of things.

当前，无线人体局域网（WBAN）正在迅速发展。可以使用现代技术开发重量轻，功耗低的微型可穿戴设备。但是，WBANs的研究挑战是功耗。本文提供了两种体内通信（IBC）方法的综述。分析了等效的人体通道模型和建模方法。回顾了传统的IBC WBANs架构，提出了新型的节能架构和IBC WBANs数据传输技术。进行实验是为了测量BodyCom移动模块的输出功率。对比分析表明，IBC提出的技术的功耗比Bluetooth LE低7倍，比ZigBee低14倍。
