Advances in soft materials, miniaturized electronics, sensors, stimulators, radios, and battery-free power supplies are resulting in a new generation of fully implantable organ interfaces that leverage volumetric reduction and soft mechanics by eliminating electrochemical power storage. This device class offers the ability to provide high-fidelity readouts of physiological processes, enables stimulation, and allows control over organs to realize new therapeutic and diagnostic paradigms. Driven by seamless integration with connected infrastructure, these devices enable personalized digital medicine. Key to advances are carefully designed material, electrophysical, electrochemical, and electromagnetic systems that form implantables with mechanical properties closely matched to the target organ to deliver functionality that supports high-fidelity sensors and stimulators. The elimination of electrochemical power supplies enables control over device operation, anywhere from acute, to lifetimes matching the target subject with physical dimensions that supports imperceptible operation. This review provides a comprehensive overview of the basic building blocks of battery-free organ interfaces and related topics such as implantation, delivery, sterilization, and user acceptance. State of the art examples categorized by organ system and an outlook of interconnection and advanced strategies for computation leveraging the consistent power influx to elevate functionality of this device class over current battery-powered strategies is highlighted.

“…The interferents used were fructose (Fru), glucose (Glu), urea (UR), uric acid (UA), and ascorbic acid (AA), in addition to DA. The concentrations of various interfering substances were chosen within the normal range of human [39][40][41][42][43]. Figure 8 shows sensors with two different structures.…”

Non-enzymatic dopamine (DA) sensors are important in diagnosing and treating human diseases. However, non-enzymatic sensors frequently encounter interference from other substances, posing a challenge of poor selectivity for such sensors. Herein, we prepared tungsten trioxide nanoparticles (WO3 NPs) via a simple hydrothermal method and immobilized them onto a cuprous oxide (Cu2O) film. The results demonstrate that WO3 NPs offer improved selectivity, thus avoiding interference from other substances. The DA sensor based on the Cu2O film modified with WO3 NPs exhibits excellent DA detection performance, with a wide linear range of 1 μM to 10 mM, a low limit of detection of 0.21 μM, and good selectivity against common interfering substances. This non-enzymatic DA sensor features a simple structure, easy fabrication, small size, and suitability for mass production.
