低功耗无线烟雾报警器的设计

传统的烟雾报警器存在高功耗且不能互联互通等问题,因而难以满足实际应用的要求。本文设计了一种低功耗无线烟雾报警器,采用低功耗、低电压的光电型烟雾探测器专用集成电路RE46C190 和超低功耗、低于1 GHz 的无线单片机CC1310,使系统待机电流大约为14 μA,理论待机寿命长达11 年,无线通信距离达到1 km,很好地满足了低功耗和无线互通的要求,为相关智慧消防建议提供了一种新的解决方案。

A flexible temperature sensing finger using optical fiber grating for soft robot application

Bionic perception, especially temperature-aware, is one of the important issues in soft robots research. This paper presents a method to implant temperature sensor network into soft robot finger by using optical fiber gratings. For avoiding strain disturbance, a dedicated metal tube is designed to package and protect the optical fiber gratings. For implanting the sensors firmly, a solution using two kinds of adhesive is proposed. The prototype is calibrated in high precision temperature bath and then measured under different temperatures and different bending conditions, respectively. The experimental results are compared with electronic temperature sensor (PT100 thermal resistance), which verifies the accuracy and repeatability of the design. With the dedicated coating and adhesive solution, the proposed temperature sensor network is suitable for implanting into soft robots for the temperature-aware ability.
