From cotton to functional flexible transparent film for printable and flexible microsupercapacitor with strong bonding interface

Abstract

Turning cotton into functional flexible transparent film is the essential step toward plentiful state-of-the-art applications. Here, cotton is transformed into functional flexible transparent film by deconstructing macroscopic cotton fibers into...

Sub-mm3 dimensional scaling of fully-integrated additively-fabricated microsupercapacitors for embedded energy storage applications

“…1,2,3,4,5 They have been used in versatile systems, such as so robots, 6 wearable electronics, 7,8,9 and they possess potential applications for Internet of Things (IoT), 10 to name a few, acting as energy storage devices. Wide ranges of materials, such as carbonaceous materials, 11,12 metal oxides, 13,14 MXenes, 15,16 and conductive polymers 17,18 have been used in these systems as the electrode active materials with the aim to maximize the performance of these systems. Depending on the energy and power requirements of the specic microelectronic system, their energy storage/delivery systems should be custom designed.…”

“…20,21 Depending on needs of the target application, it is crucial to fabricate these energy storage systems with the appropriate footprint while fullling the requisite power and energy requirements. Given the interest in integration within microelectronic systems, there have been numerous reports on the fabrication of microsupercapacitors through rapid and exible fabrication methods, 12,22,23,24,25 on the other hand, the realized devices have generally been larger than mandated by real application demands, and dimensional scaling studies on these systems have been very rare. There have been some dimensional scaling studies performed on microsupercapacitors, but these have been mostly focused on microsupercapacitors fabricated through conventional subtractive microfabrication techniques, and the electrodes used (carbon nanobers, 26 graphene 27 and RuO 2 (ref.…”
