| description | Advanced functional fibers enable traditional fabrics to perform a variety of functions, including energy harvesting/storage, sensing, information communication, and display, and they show promise in a wide range of fields due to their flexibility and abrasion resistance. At the same time, these interactive fabrics can sense and respond to a wide range of physical and environmental stimuli, such as pressure, temperature, motion and biological signals. Their key features include lightweight construction, high sensitivity, versatility and scalability. In addition, they are typically washable and can be adapted to a variety of fabric textures, ensuring their utility in everyday life.
This thesis begins with an introduction to cobalt hydroxide, and how this material can be combined with carbon nanotubes to prepare flexible fiber electrodes and assemble ionic devices to demonstrate a specific example of flexible fibers with hysteretic biosignaling properties, which illustrates the amazing potential of applications of electrodes with flexible fiber materials.
Subsequently, the current-voltage and voltage-current characteristics of the ionic device are tested and explained in depth by constructing a circuit model. After analyzing the test data, it is found that the ionic device has synapse-like long timerange plasticity, whose short time-range plasticity is complemented by the introduction of the ion recycling mechanism.
Finally, a circuit design including MCU, communication module, voltage conversion module, electrical stimulation module, thermoelectric module, mechanical actuator module, and multiplexer is constructed to sample the crossbar currents or voltages so as to represent the phenomenon of resistive jumps of the fiber arrays, which is of great significance for multifunctional fibers applications. |
