N2 - One of the challenges in embedding sensors inside concrete and pavement highways is to be able to power and wirelessly interrogate these devices in real-Time without taking the structure out-ofservice. In this paper, we report a hybrid-powered H-gauge sensing platform that can be embedded inside pavements and can operate for years without any maintenance. This sensor platform is general enough to support a variety of transducers that operate in parallel and can wirelessly transmit relevant information to an external interrogator. Each sensor was equipped with a passive wake up circuitry that connects an embedded battery to the micro-controller only when it receives a valid signal from the interrogator. In this paper, we present prototypes of the hybrid sensor by integrating commercial off the shelf components along with temperature and humidity sensor and a custom built piezo-floating gate (PFG) sensor, that can continuously log cumulative strain statistics. In this paper, we also explore a completely self-powered variant of the platform that harvests the energy from the interrogator, as well as a quasi-self-powered platform that is designed to support long-range wireless interrogation. Deployment studies have bee conducted to determine the practical challenges and long-run performance of the proposed prototypes.
