Recent advances in stretchable field-effect transistors
2021
Stretchable field-effect transistors (s-FETs), a indispensable component in stretchable electronics, have emerged as a noteworthy technology in the academic and industrial communities due to their broad application prospects, especially in wearable electronics, implantable electronics and skin-like electronics. Currently, significant efforts have been devoted to fabricating high-performance s-FETs, and remarkable advances in material, structural, processing techniques and applications have been achieved. Here, we summarize recent progress in the fabrication of high-performance s-FETs achieved by developing advanced stretchable channel materials, structural designs and processing techniques. Moreover, the applications of s-FETs in stretchable electronics, such as stretchable sensors, stretchable memory transistors and stretchable artificial neurologically devices, are discussed. Beyond discussing recent key work in this field, current challenges and prospective directions of s-FETs in stretchable electronics are also discussed. This review presents a detailed overview of recent progress in s-FET fabrication and applications, which provides a guideline for the further development of s-FETs with high stretchability and electrical performance in the near future.
