近期，美國軍事部門DARPA正在開發(fā)一種可以看到墻后物體的生物傳感器。當遇到墻壁和路障，我們無法看后后面的物體，這對人們尤其是軍事部門的人很不方便。

生物傳感器模型

　　該計劃被稱為“生物識別技術(shù)AT-T距離”，定義為：根據(jù)DARPA的項目計劃結(jié)合了前兩個：墻壁，后面可以看到雷達的范圍，而且可以檢測背后的墻壁人的心跳。

　　熱到熱像儀的活體墻回檢測超出了DARPA可能的，也可看到至少10米。遵循背后的心臟的電活動的人的生理功能墻，也可以檢測。

　　這項技術(shù)可檢測多達10人在一個房間里。DARPA的倡議，特別是在恢復(fù)操作或盡量減少生命損失和修復(fù)策略，以不傷害無辜的目標。（生物谷Bioon.com）

DARPA’s Sensors will Pick up Your Heartbeat in a Crowd

Soon the U.S. military will have something akin to X-ray vision. Researchers at the Defense Advanced Research Projects Agency are working on improving its sensors to track a person's heartbeat through walls and even pinpoint it in a crowd.

Called "Biometrics-at-a-distance," DARPA's program seeks to build sensors that can record human vital signs greater than 10 meters using non-line-of-sight methods and do so for up to 10 people at the same time.

The program will essentially be a blend of two existing Pentagon projects: the Radar Scope and the LifeReader. The Radar Scope was developed in 2006 and uses radar waves to see through walls and detect the subject's breathing. The Life Reader is a system that uses Doppler radar to find heartbeats. The military has also been using scanners like "Sense Through the Wall" and TiaLinx's Eagle scanner that can detect the presence of humans and animals through walls.

DARPA seeks a system that can combine all these technologies into one device that can do it better. It's planned "Biometrics-at-a-distance" will be able to see much farther than current sensors. Some see-through devices can only see through eight inches of concrete, but DARPA is working on a device to see farther than 10 meters in crowded areas. Seeing or "sensing" if there are enemies through walls will be a big help to troops and even police officers who will be one step ahead of what's on the other side of the door.

DARPA is also adding another feature that will make it harder for fugitives to hide from their sensors. A person's heartbeat is unique to the individual so DARPA is going to use electrocardiography, the analysis of the heart's electrical activity to identify up to 10 different individuals.

The new sensor won't just be used for military applications. Having the ability to find heartbeats will be helpful in disaster rescue efforts where victims could be trapped under miles of rubble.
