本课题采用MEMS工艺制作热膜式气体质量流量传感器，主要工作放在敏感头芯片部分的研制。

This task adopt MEMS technics to make Thermal -film air-mass sensor, mostly work is the study and facture of the sense organ of the chip.

这种智能芯片比火柴头还稍小，而现今最好的植入物却仅仅是如火柴盒一样大小，这种芯片通过阻断传向大脑的疼痛信号来发挥作用。

Slightly smaller than the head of a match - the best implants today are only as small as a matchbox - the chip works by blocking pain signals on their way to the brain.

于是，一些无线芯片，比如用于全球定位系统的芯片或者用于蓝牙无线通讯的芯片现在每个只卖1美元，而体积只有火柴头那么大。

As a result, some radio chips—for example, those used for the Global Positioning System, say, or for Bluetooth wireless communications—now cost as little as $1 and are the size of a matchhead.
