Flexible/Stretchable Electronics

Dear Colleagues,

Exciting achievements have been produced towards the rapid growth of flexible and stretchable electronics technology, such as rollable displays, electronic eye cameras, conformable wearable sensors, and health monitoring devices. These electronic devices are more essentially designed, with excellent mechanical deformability, possessing sensitive-to-multifunctional responses, smart human–machine interactions, and intelligent control capabilities. However, the most common and critical issue that hinders the performances of the flexible and stretchable electronics is the maintenance of device performance under external deformations. Thus, the development of material design and engineering should focus on the realization of flexibility and stretchability. Although, intrinsically flexible and stretchable materials show potential applications, their electrical performances remain incomparable with those of conventional electronic materials. Recently, hierarchical architectures inspired by nature have greatly enhanced the potential applications in novel flexible devices. Thus, innovative breakthroughs in advanced materials, through unique geometrical designs that are mechanically robust, have drawn extensive attention in the field of flexible and stretchable device engineering. Moreover, combinations of these electronic devices, with more emphasis on miniaturization, multifunctional sensing and battery-free wireless communications, enable fruitful future flexible and stretchable electronic devices.

The main aim of this Special Issue is to seek high-quality submissions that highlight emerging applications, address recent breakthroughs in flexible and stretchable electronic system-innovative geometrical designs, device architectures, facile fabrication methodologies, smart electronic devices with multifunctionalities, and battery-free wireless communication. The topics of interest include, but are not limited to:

• Flexible and stretchable electronics for biomedical applications
• Multifunctional smart sensors
• Battery free, wireless electronic devices
• Power supply, generation, and storage in stretchable electronics
• Scalable high throughput and facile fabrication procedures for the realization of scientific technological growth and development
• Robust and reliable novel geometrical designs for high performance stretchable electronic devices
