Special Issue Information

Dear Colleagues,

Recently, flexible/stretchable electronics configured in soft, shape-conformable formats have gained great research interest due to their promising applications in bioelectronics, such as personal health monitoring, human–machine interactions, implantable devices, etc., and enormous progress has been made in new materials, structural designs, and nano-fabricating techniques for flexible/stretchable bioelectronics.

Among various flexible/stretchable bioelectronics, nanomaterials-based stretchable sensors have witnessed great advances with the continued development of nanomaterials, such as metal nanowires, CNTs, graphene, transition metal dichalcogenides, polymer semiconductors, etc. These emerging nanomaterials are essential technologies to help resolve the intrinsic mechanical mismatch between electronic devices and biological curvilinear surfaces. And nanomaterial-based devices possess several unique mechanical and electrical characteristics that enable flexible bioelectronics with excellent performances, such as self-healability, good stretchability, high conductivity, and great sensitivity.

In this Special Issue, titled “Nanomaterials-Based Stretchable Sensors for Bioelectronics” in Nanomaterials, we invite potential authors to submit manuscripts focused on nanomaterials that could promote multifunctional applications of stretchable sensors for bioelectronics. We welcome original research, review, mini-review, and perspective articles on themes including, but not limited to, the following:

  • Nanomaterial synthesis, characterization, and optimization for flexible/stretchable sensors;
  • Nanomaterials-based device for implantable bioelectronics;
  • Nanomaterials for stretchable epidermal electronics;
  • Nanomaterials for flexible multifunctional sensors;
  • Nanomaterials for stretchable synaptic transistors;
  • Design strategy for nanomaterials-based stretchable sensors;
  • New manufacturing techniques for nanomaterials-based stretchable sensors;
  • Multifunctional integration of nanomaterials for bioelectronics.

Electrophysiological monitoring is a commonly used medical procedure designed to capture the electrical signals generated by the body and promptly identify any abnormal health conditions. Wearable sensors are of great significance in signal acquisition for electrophysiological monitoring. Traditional electrophysiological monitoring devices are often bulky and have many complex accessories and thus, are only suitable for limited application scenarios. Hydrogels optimized based on nanomaterials are lightweight with excellent stretchable and electrical properties, solving the problem of high-quality signal acquisition for wearable sensors. Therefore, the development of hydrogels based on nanomaterials brings tremendous potential for wearable physiological signal monitoring sensors. This review first introduces the latest advancement of hydrogels made from different nanomaterials, such as nanocarbon materials, nanometal materials, and two-dimensional transition metal compounds, in physiological signal monitoring sensors. Second, the versatile properties of these stretchable composite hydrogel sensors are reviewed. Then, their applications in various electrophysiological signal monitoring, such as electrocardiogram monitoring, electromyographic signal analysis, and electroencephalogram monitoring, are discussed. Finally, the current application status and future development prospects of nanomaterial-optimized hydrogels in wearable physiological signal monitoring sensors are summarized. We hope this review will inspire future development of wearable electrophysiological signal monitoring sensors using nanomaterial-based hydrogels. Full article
