Biothermal Sensing of a Torsional Artificial Muscle
(Royal Soc Chemistry, 2016-01-25)
Biomolecule responsive materials have been studied intensively for use in biomedical applications as smart systems because of their unique property of responding to specific biomolecules under mild conditions. However, ...
A New Catalyst-Embedded Hierarchical Air Electrode For High-Performance Li-O₂ Batteries
(2013-06-05)
The Li-O₂ battery holds great promise as an ultra-high-energy- density device. However, its limited rechargeability and low energy efficiency remain key barriers to its practical application. Herein, we demonstrate that ...
High-Performance Biscrolled MXene/Carbon Nanotube Yarn Supercapacitors
Yarn-shaped supercapacitors (YSCs) once integrated into fabrics provide promising energy storage solutions to the increasing demand of wearable and portable electronics. In such device format, however, it is a challenge ...
Orthogonal Pattern of Spinnable Multiwall Carbon Nanotubes for Electromagnetic Interference Shielding Effectiveness
(Elsevier Ltd, 2019-05-02)
The need for thin and lightweight electromagnetic interference shielding materials is rapidly increasing in several industries, such as aerospace and telecommunication. This research finds that a shielding material, which ...
Enhancement of Electromagnetic Interference Shielding Effectiveness with Alignment of Spinnable Multiwalled Carbon Nanotubes
(Pergamon-Elsevier Science Ltd, 2018-10-23)
This research develops a unique material to attenuate electromagnetic interference (EMI) by using spinnable multiwalled carbon nanotubes (MWNTs) combined with bio-polydimethylsiloxane (PDMS) that contains BaTiO₃ (MBPBT). ...
Harvesting Electrical Energy from Torsional Thermal Actuation Driven by Natural Convection
The development of practical, cost-effective systems for the conversion of low-grade waste heat to electrical energy is an important area of renewable energy research. We here demonstrate a thermal energy harvester that ...
Conductive Functional Biscrolled Polymer and Carbon Nanotube Yarns
(2013-10-10)
Biscrolling aligned electrospun fiber (AEF) sheets and carbon nanotube (CNT) sheets were fabricated for conductive, functional yarns by a versatile dry composite method. Our biscrolling (twist-based spinning) method is ...
Magnetic Torsional Actuation of Carbon Nanotube Yarn Artificial Muscle
Magnetically driven torsional actuation of a multiwalled carbon nanotube (MWNT) yarn was realized by first biscrolling NdFeB magnetic particles into helical yarn corridors to make a magnetic MWNT yarn. The actuating device ...
Bio-Inspired, Moisture-Powered Hybrid Carbon Nanotube Yarn Muscles
Hygromorph artificial muscles are attractive as self-powered actuators driven by moisture from the ambient environment. Previously reported hygromorph muscles have been largely limited to bending or torsional motions or ...
Highly Stretchable Hybrid Nanomembrane Supercapacitors
(2016-03-04)
Supercapacitors that are lightweight, mechanically deformable (stretchable, flexible) and electrochemically stable have potential for various applications like portable, wearable, and implantable electronics. Here we ...
