本文研究了RF能量采集器的功率转换效率(PCE)对无线物联网(IoT)设备性能的影响,包括采样率和数据安全性。设计了一种从2.64 GHz的工作频率采集能量的RF能量采集器,并将其原型化用于测量。微控制器单元(MCU)采用具有128位密钥的微型加密算法(TEA)进行数据加密。测量结果表明,随着能量收集量的增加,最大采样率和数据的安全性也可以增加。这意味着功率转换效率(PCE)对自供电无线物联网设备的数据速率和数据安全性都有影响。
This paper presents a study on the impact of the power conversion efficiency (PCE) of RF energy harvesters on the performance of wireless Internet-of-Things (IoT) devices including the sampling rate and data security. An RF energy harvester to harvest energy from the career frequency of 2.64 GHz is designed and prototyped for measurements. A microcontroller unit (MCU) adopts Tiny Encryption Algorithm (TEA) with a 128-bit key for data encryption. Measurement results indicate that as the amount of energy harvested increases, the maximum sampling rate and the security of the data can also increase. It implies the power conversion efficiency (PCE) impacts on both the data rate and data security of self-powered wireless IoT devices.
