Hacker News Daily 上看到「Towards Battery-Free HD Video Streaming」這個,不使用電池僅靠反射產生訊號,可以達到 HD 畫質的 Camera Streaming (在原型機上測試可以跑出 720p/10fps):

Finally, we design a proof-of-concept prototype with off-the-shelf hardware components that successfully backscatter 720p HD video at 10 fps up to 16 feet.

而且畫質比想像中好很多,算是比「可用」的等級還高不少:

愈來愈多在研究用 backscatter 拼一些比較複雜的應用...
