A batteryless remote control and a corresponding receiver system for home Internet of Things (IoT) applications are proposed. The user board backscatters a carrier signal in accordance with a user’s click pattern. The backscattered signal is captured using a low-end radio-frequency (RF) receiver, and a receiver algorithm detects the pattern and identifies the corresponding user command. Our testbed evaluation demonstrates 100% accuracy at up to 3 m.

无能为力的 IoT Clicker 系统


提出了一种用于家庭物联网（IoT）应用的无电池遥控器和相应的接收器系统。用户板根据用户的点击模式反向散射载波信号。使用低端射频 (RF) 接收器捕获反向散射信号，接收器算法检测该模式并识别相应的用户命令。我们的测试台评估表明，在 3 m 以内的精度为 100%。
