Marine animals equipped with sensors provide vital information for understanding their ecophysiology and collect oceanographic data on climate change and for resource management. Existing methods for attaching sensors to marine animals mostly rely on invasive physical anchors, suction cups, and rigid glues. These methods can suffer from limitations, particularly for adhering to soft fragile marine species such as squid and jellyfish, including slow complex operations, unreliable fixation, tissue trauma, and behavior changes of the animals. However, soft fragile marine species constitute a significant portion of ocean biomass (>38.3 teragrams of carbon) and global commercial fisheries. Here we introduce a soft hydrogel-based bioadhesive interface for marine sensors that can provide rapid (time <22 s), robust (interfacial toughness >160 J m−2), and non-invasive adhesion on various marine animals. Reliable and rapid adhesion enables large-scale, multi-animal sensor deployments to study biomechanics, collective behaviors, interspecific interactions, and concurrent multi-species activity. These findings provide a promising method to expand a burgeoning research field of marine bio-sensing from large marine mammals and fishes to small, soft, and fragile marine animals.

“…Sensors, transcending their conventional roles, have redefined established techniques and methodologies. Their far-reaching impact spans critical domains such as food safety, environmental screening, drug development, and clinical applications, embodying three fundamental components: a sensing element, a transducer, and a detector [10][11][12][13][14][15]. The sensor operates on a fundamental principle-target molecules interacting with a sensing element, which, in turn, recognizes these molecules through intricate physical and/or chemical interactions.…”

In the realm of sensing technologies, the appeal of sensors lies in their exceptional detection ability, high selectivity, sensitivity, cost-effectiveness, and minimal sample usage. Notably, molecularly imprinted polymer (MIP)-based sensors have emerged as focal points of interest spanning from clinical to environmental applications. These sensors offer a promising avenue for rapid, selective, reusable, and real-time screening of diverse molecules. The preparation technologies employed in crafting various polymer formats, ranging from microparticles to nanomaterials, wield a profound influence. These techniques significantly impact the assembly of simplified sensing systems, showcasing remarkable compatibility with other technologies. Moreover, they are poised to play a pivotal role in the realization of next-generation platforms, streamlining the fabrication of sensing systems tailored for diverse objectives. This review serves as a comprehensive exploration, offering concise insights into sensors, the molecular imprinting method, and the burgeoning domain of MIP-based sensors along with their applications. Delving into recent progress, this review provides a detailed summary of advances in imprinted-particle- and gel-based sensors, illuminating the creation of novel sensing systems. Additionally, a thorough examination of the distinctive properties of various types of MIP-based sensors across different applications enriches the understanding of their versatility. In the concluding sections, this review highlights the most recent experiments from cutting-edge studies on MIP-based sensors targeting various molecules. By encapsulating the current state of research, this review acts as a valuable resource, offering a snapshot of the dynamic landscape of MIP-based sensor development and its potential impact on diverse scientific and technological domains.

Wearable, implantable, and environmental (WIE) "edge" sensors, being deployed for a broad range of applications including smart healthcare and agriculture, are typically powered by various active (e.g., triboelectric generator, solar cell, etc.) and passive (e.g., drone-supported RFID) energy harvesters. Unfortunately, these active and passive harvesters rely on intermittent sources of energy, and additional circuitry needed to integrate the harvester with the sensor increases design cost and complexity. Interestingly, this problem can be resolved if the sensor can power itself by time-multiplexed harvesting of the energy contained in the signal/noise. These "dual-function" sensors have been previously used in selfpowered microphones, cameras, biofuel cells, etc. Since a potentiometric ion-selective electrode (ISE) measures analyte concentration in the form of a voltage signal, in principle, the voltage can be used to self-power the ISE system, including the signal readout and processing circuitry. The principle has already been demonstrated for the self-powered reading of the voltage signal; however, a long-term analysis of the viability and reliability of ISE sensing and harvesting is needed for integration into continuous monitoring edge devices. In this paper, we develop an equivalent circuit model of ISE from electrochemical impedance analysis to quantify its key reliability issues such as voltage stability, sensitivity, and power harvesting capacity by repetitive charging and discharging of a capacitor. The circuit model is verified by a systematic set of laboratory experiments. We show that an unoptimized pH sensor can harvest 0.12 nW/cm 2 while simultaneously measuring the analyte activity for days; the experimental evidence indicates that the sensing and harvesting can continue indefinitely. Using the circuit model as an optimization tool, we experimentally show that power yield can be increased approximately 500 times to 50 nW/cm 2 by replacing the pH sensor with bare Pt wire, demonstrating the potential of such harvesters.
