英文摘要	Ultrasound-induced energy transfer (UET) represents an emerging technology that can be integrated into implantable medical systems for wireless power and information communication applications. However, the spatial-temporal resolution, directivity, and versatility of traditional piezo-ultrasound systems are generally limited. Here, we describe the novel design and implementation of a hybrid-induced energy transfer strategy using photoacoustic (PA) and piezo-ultrasound (PU) technology in a 3D twining wireless implant, which shows multi-mode transmission advantages, with high power, better resolution, and flexible directivity. This new ultrasonic system exploits a focused ring piezo-transducer and a miniaturized fiber-photoacoustic converter as the hybrid acoustic source and a (K,Na)NbO3-based lead-free linear piezo-array as the harvester. Complying with FDA regulations, hybrid-induced multifunctionality, such as stable powering (∼21.3 mW cm-2) and the high-resolution signal communication (signal-to-noise ratio: ∼22.5 dB) of a two-dimensional image, was demonstrated ex vivo using 12 mm-thick porcine tissue. The 3D twining design also ensures that the device can achieve stable energy harvesting without operational difficulties, a unique advantage that can facilitate its future clinical application. © 2021 The Royal Society of Chemistry.
