Soft materials for wearable supercapacitors

Abstract

Along with the experienced rapid progress of wearable and portable electronic devices including electrical sensors, flexible displays, and health monitors, there is an ever-growing demand for wearable power sources. Supercapacitors as a new kind of energy storage device have received considerable attention for decades due to their high-power density, excellent cycling stability and easy fabrication. To fulfill the demand of wearable power sources, wearable supercapacitors are also further developed and studied. Newly electrode materials which play a significant role in

Bioadhesive and electroactive hydrogels for flexible bioelectronics and supercapacitors enabled by a redox-active core–shell PEDOT@PZIF-71 system

“…In this regard, functional electrodes have been extensively studied for their sensing role but also their indispensable role as functional energy supply alternatives for wearable/portable bioelectronic devices. [1][2][3][4] However, most functional electrodes are fabricated with a focus on sensing or energy storage. 5 Developing bioelectronics that can integrate multiple functions has not been achieved.…”

Integrating recyclable polymers into thermoelectric devices for green electronics

“…TEGs were chosen owing to their technological importance, and their robustness against wear and tear. [22][23][24] They can be used to harvest electrical energy from environmental waste heat. Vice versa, thermoelectrics (TEs) can also be used to convert electricity into heat pumps, serving as solid state refrigeration.…”

Polyurethane vitrimers: Chemistry, properties and applications

“…Thanks to the static chemical crosslinking structure, PUs exhibit prime structural stability, chemical stability, thermal stability, mechanical strength, and creep resistance 1,2 . PUs have been widely used as adhesives, foams, coatings, and elastomers in various fields, including biomedical engineering, electronics, transportation, agriculture, sports devices, packaging, construction, national defense, and so forth 3–8 . Although PUs exhibit tremendous excellent properties, they still suffer from mechanical damage during their long‐term applications, leading to a dramatic decrease in the safety and service life 9–11 .…”

“…1,2 PUs have been widely used as adhesives, foams, coatings, and elastomers in various fields, including biomedical engineering, electronics, transportation, agriculture, sports devices, packaging, construction, national defense, and so forth. [3][4][5][6][7][8] Although PUs exhibit tremendous excellent properties, they still suffer from mechanical damage during their long-term applications, leading to a dramatic decrease in the safety and service life. [9][10][11] On the other hand, the self-healing capability of thermosetting PUs has been limited by the presence of crosslinking structures through covalent bonds.…”
