为了真正从物联网（IoT）带来的前所未有的可能性中受益，需要大规模部署无线传感器节点（wsn）来持续检测物理、生物或化学参数。就在最近，通过利用先进的片上设计和微加工工艺，已经展示了具有更高灵敏度的新传感器。然而，使用这种传感器的wsn需要能量来传输被感知的信息。因此，它们要么包含需要定期更换的电池，要么包含低效率的能量收集电路，这些电路阻碍了频繁和连续的传感，并影响了通信的最大范围。在这里，我们报告了一种新的无芯片和无电池的基于标签的无线传感器网络，从根本上打破了以往的任何范式。该WSN由印刷基板上现成的集总组件组成，可以在不需要供电或收集直流电源的情况下感知和传输信息，同时支持全双工收发器设计，用于询问节点，使其免受自身干扰。此外，尽管报道的WSN不需要任何先进和昂贵的制造，但其独特的参数动态行为使其具有非凡的灵敏度和动态范围，甚至可以超越片上传感器。报道了这种新型无线传感器网络的首次实现的操作和性能。该设备在超高频范围内工作，能够被动地、连续地从询问节点远程检测温度变化。
Massive deployments of wireless sensor nodes (WSNs) that continuously detect physical, biological or chemical parameters are needed to truly benefit from the unprecedented possibilities opened by the Internet-of-Things (IoT). Just recently, new sensors with higher sensitivities have been demonstrated by leveraging advanced on-chip designs and microfabrication processes. Yet, WSNs using such sensors require energy to transmit the sensed information. Consequently, they either contain batteries that need to be periodically replaced or energy harvesting circuits whose low efficiencies prevent a frequent and continuous sensing and impact the maximum range of communication. Here, we report a new chip-less and battery-less tag-based WSN that fundamentally breaks any previous paradigm. This WSN, formed by off-the-shelf lumped components on a printed substrate, can sense and transmit information without any need of supplied or harvested DC power, while enabling full-duplex transceiver designs for interrogating nodes rendering them immune to their own self-interference. Also, even though the reported WSN does not require any advanced and expensive manufacturing, its unique parametric dynamical behavior enables extraordinary sensitivities and dynamic ranges that can even surpass those achieved by on-chip sensors. The operation and performance of the first implementation of this new WSN are reported. This device operates in the Ultra-High-Frequency range and is capable to passively and continuously detect temperature changes remotely from an interrogating node.
