Next-generation clean energy technology provides a promising solution for the forthcoming fossil fuel-based energy crisis. However, before being extensively employed as major power generation supplies, these clean-energy power sources may first find practical applications in portable electronics, such as advanced sensing systems. Taking advantage of unique structural characteristics and versatile physical properties of nanomaterials, such as large surface-to-volume ratio and short pathways for charge transport, advanced sensors with ultrahigh sensitivity and fast response have been extensively developed.

We invite investigators to contribute original research articles as well as review articles which can stimulate the development of more efficient clean energy solutions and smarter advanced sensor networks and attract broad interest from the whole scientific community. We are particularly interested in articles describing functional devices for energy harvesting/conversion/storage in a clean and efficient manner and advanced nano/microsensors with high sensitivity and fast response.

Potential topics include, but are not limited to:

• Newly designed high efficiency solar cells and fuel cells
• High-performance lithium-ion batteries
• Mechanical energy harvesting and storage devices
• Ultrasensitive nano/microsensors
• Self-powered smart sensor networks
