There are two main issues about embedded sensor network based on Bluetooth to be resolved: the topology formation arithmetic of Bluetooth scatternet and the design of Bluetooth sensor node system.

基于蓝牙技术的嵌入式传感器网络研究主要解决两个问题：一是蓝牙散射网拓扑结构形成算法的研究；二是嵌入式蓝牙传感器节点的设计。

The material uses what the researchers are calling 'shape-memory' polymers and have a fiber optic network embedded within them which acts as the damage sensor as well as the heat delivery system.
