Topic: Energy materials for wearable, implantable electronics and bioMEMS

Flexible, wearable and implantable electronics, and BioMEMS, are rapidly evolving fields attracting significant interest from multiple disciplines and communities as they are playing an increasingly important role in healthcare, disease diagnosis, multimorbidity monitoring and management, personalized therapeutics, and lab-on-chip diagnostics. However, their advancement is still limited by the lack of suitable, long-lasting, and miniaturized energy sources. Wearable and implantable batteries, along with micro-energy devices such as piezoelectric, triboelectric, thermoelectric micro/nanogenerators, are among the most promising solutions. Although substantial progress has been made in the relevant areas, further developments and improvements in materials, design, performance, energy efficiency and miniaturization are still required. In addition, major challenges remain in system integration, long-term stability, biocompatibility and biodegradability, demanding continued research and innovation.

This Special Issue aims to explore recent advances in micro-energy technologies, including smart energy materials, flexible and stretchable therapeutic devices, wearable or implantable energy storage solutions, self-powered wireless sensing, energetic therapy technologies, and active drug delivery or wound healing platforms, bringing these technologies closer to practical deployment in future wearable and implantable systems, or BioMEMS.
