The study, led by Associate Dean Chen Xiaodong of the School of Materials Science and Engineering at Nanyang Technological University, published in the January 8 issue of Advanced Materials, said that the fabric capacitor material is a big step beyond the existing technology - - Existing materials are produced in a fixed shape and size, and the new material can be extended in many directions with better charge and discharge performance. Even after stretching to four times the original length, after charging and discharging 10,000 times Can maintain nearly 98% of the storage capacity.
The new material when assembled into a honeycomb structure can achieve four times the current storage capacity of the material.
The fabric is capacitively tied to the tester's elbow and maintains a more steady signal flow than existing materials as the arm waves, benefiting the signal transmission between the capacitor and other wireless devices, such as transmitting patient heart rate data.
Researchers say the new material can be produced using existing production techniques, so the cost of the new material is also very low, estimated at just about 10 cents per square centimeter.
Professor Chen said: 'Reliable, editable capacitor materials for the development of wearable electronic equipment industry is crucial, when the wearable electronic devices can be self-sustaining power supply, you can home or other environment, a variety of electrical connections and let them This opens up all kinds of opportunities for the development of the Internet of Things.
This new capacitive material is made of a manganese dioxide nanowire composite material and is reinforced by the addition of carbon nanotubes and nanocellulose fibers that allow the electrode to withstand the stresses of the material as it is stretched.
Professor Chen said he has a dream that one day flexible capacitive materials can be used in health and sports fields with wearable devices. For example, its high sensitivity enables real-time monitoring of marathon runners' various body states during running, analysis of outgoing data, and more.
