摘要

我们提出了一个2×4×4mm3成像系统,包括光学,无线通信,电池,电源管理,太阳能收集,处理器和存储器。该系统具有160×160分辨率CMOS图像传感器,具有304nW连续像素内运动检测模式。系统组件在五个不同的IC层中制造,并以最小的形式堆叠。光伏(PV)电池面向成像仪的相反方向,以获得最佳照明,并在10klux下产生456nW,使能源自主系统运行。

A millimeter-scale wireless imaging system with continuous motion detection and energy harvesting
We present a 2×4×4mm3 imaging system complete with optics, wireless communication, battery, power management, solar harvesting, processor and memory. The system features a 160×160 resolution CMOS image sensor with 304nW continuous in-pixel motion detection mode. System components are fabricated in five different IC layers and die-stacked for minimal form factor. Photovoltaic (PV) cells face the opposite direction of the imager for optimal illumination and generate 456nW at 10klux to enable energy autonomous system operation.
