“…For instance, while improving sensor selectivity, it is crucial to ensure that an improvement does not compromise sensor sensitivity and stability. In addition, most studies are conducted in laboratory conditions, and the transition to real-world applications demands the consideration of factors such as temperature, humidity, and fluctuations in the ion concentrations [31][32][33][34]. While we face numerous challenges, our primary focus remains on unraveling the mechanisms and patterns underlying the conformational changes in PEG in response to environmental variations.…”

Polyethylene glycol (PEG) is an artificial polymer with good biocompatibility and a low cost, which has a wide range of applications. In this study, the dynamic response of PEG single chains to different ion concentrations was investigated from a microscopic point of view based on single-molecule force spectroscopy, revealing unique interactions that go beyond the traditional sensor-design paradigm. Under low concentrations of potassium chloride, PEG single chains exhibit a gradual reduction in rigidity, while, conversely, high concentrations induce a progressive increase in rigidity. This dichotomy serves as the cornerstone for a profound understanding of PEG conformational dynamics under diverse ion environments. Capitalizing on the remarkable sensitivity of PEG single chains to ion concentration shifts, we introduce innovative sensor-design ideas. Rooted in the adaptive nature of PEG single chains, these sensor designs extend beyond the traditional applications, promising advancements in environmental monitoring, healthcare, and materials science.

The next‐generation bionics and, more specifically, wearable and implantable bioelectronics require wireless, battery‐free, long‐term operation and seamless bio‐integration. Design considerations, materials choice, and implementation of efficient architectures have become crucial for the fabrication and deployment of wireless devices, especially if they are flexible or soft. Wireless power and data transfer represent key elements for the development of robust, efficient, and reliable systems for health monitoring, advanced disease diagnosis and treatment, personalized medicine. Here, the recent advances in materials and technologies used for wireless energy sourcing and telemetry in bio‐integrated flexible bionic and bioelectronic systems are reviewed. The study tackles different challenges related to mechanical compliance, low thickness, small footprint, biocompatibility, biodegradability, and in vivo implementation. The work also delves into the main figures of merit that are mostly adopted to quantify the wireless power/data transfer performances. Lastly, the pivotal applications of wearable and implantable wireless bionics/bioelectronics are summarized, such as electrical stimulation/recording, real‐time monitoring of physiological parameters, light delivery trough optical interfaces, electromechanical stimulation via ultrasounds, highlighting their potential for future implementation and the challenges related to their commercialization.
