摘要

本文提出了一种可由智能手机供电和控制的超低功耗全光便携式无电池嵌入式微系统。微系统包含一个超低电压微控制器作为处理单元;它通过一个微型太阳能电池获得能量。光驱动的微控制器读取本地传感器数据，并通过调制LED的光将其传输到移动电话。为该系统设计了一种基于脉冲周期调制的自定义光通信协议。还编写了利用手机内置闪光灯的基于图像处理的移动应用程序，用于控制微系统。使用内置后置摄像头的手机应用程序对微系统上的LED调制光信号进行分析，并提取传输数据。并给出了各种局部温度测量的实验结果。

Optically Powered Battery-Free Portable Microsystem for WSN and IoT Applications

This paper presents an ultra low power all-optical portable battery-free embedded microsystem that can be powered and controlled by a smart mobile phone. The microsystem contains an ultra-low voltage microcontroller as the processing unit; and, it receives power via a mini-solar cell. The optically powered microcontroller reads the local sensor data and transmits it to the mobile phone via modulating the light of an LED. A custom optical communication protocol that is based on Pulse Period Modulation is designed for the system. An image processing based mobile application utilizing the built-in flash of the phone is also programmed for controlling the microsystem. The mobile phone application using the built-in rear-facing camera analyzes the modulated optical signal from the LED on the microsystem and extracts the transmitted data. Experimental results of various local temperature measurements are also given.
