A system to wirelessly convey electric energy through a thin metal wall is proposed in the paper, where 2 piezoelectric transducers are used to realize energy transformation between electric and mechanical, and a rechargeable battery is employed to store the transmitted energy. To integrate them as a whole, an interface of a modulating circuit is applied between the transducer system and the storage battery. In addition, a synchronized switch harvesting on inductor in parallel with the transducer system is introduced to artificially extend the closed interval of the modulating circuit. The process of transmitting energy is computed, and the performance of the transducer system is optimized in detail for a prescribed external electric source. The results obtained are useful for understanding and designing wireless energy supply systems.

This paper develops an energy-aware and throughsubstrate sensor network using a Pulse Switching (PS) architecture for Structural Health Monitoring applications. Pulse Switching based protocols as developed in our prior work use single pulses instead of multi-bit packets for information delivery with ultra high energy-efficiency. Such packet-less networking is shown to be sufficient for event monitoring applications with binary sensing requirements. Pulse Switching using ultrasound, in particular, is well suited for communication through metal/composite substrates used in structures such as bridges, aircraft wings, etc. This paper presents a joint MAC-Routing architecture and its associated algorithms for Pulse Switching using an ultrasonic through-substrate physical layer. It also develops novel energy-aware protocol syntaxes in the PS domain for reliable operation in intermittently energy-constrained systems such as those powered by vibration energy harvesting. Experimental evaluation of a through-substrate pulse modem and ultrasonic pulse data-link is presented for demonstrating the feasibility of a pulse based ultrasonic physical layer. Using simulation experiments, it is shown that the proposed energyaware mechanisms can offer a performance-enhanced throughsubstrate network that can be reliably used for structural health monitoring using energy harvested from structure vibrations.

“…These signals were transmitted using a frequency-hopping scheme, and modulation schemes of differential phase-shift keying and quadrature amplitude modulation were compared. Saulnier et al worked to communicate ultrasound through a 6-in steel wall [14]. The research in [14] describes three approaches for communicating through the steel block: a double-hop approach, a reflectedpulse approach, and an approach consisting of a hybrid between the two.…”
