Tailoring transfer dynamics of mobile cations across solid-state electrolyte-electrode interfaces is crucial for high-performance electrochemical soft actuators. In general, actuation performance directly proportional to the affinity and anions in electrolyte opposite electrode surfaces under an applied field. Herein, maximize actuation, we report electronically conjugated polysulfonated covalent organic framework ( p S-COF) used as a common host 1-ethyl-3-methylimidazolium cation embedded...
Abstract The versatility of fingers stems from their ability to interact with surroundings by taking poses, performing various grasping modes, and making dynamic bending motions. However, conventional glove‐type wearable interfaces often fail fully engage the structural diversity motions fingers, providing tactile feedback limited areas restricting full utilization finger for rich interactions. Here, a auxetic haptic (GAWH) interface that employs an meta‐design offer embodied mechanical...
Abstract Electro‐ionic artificial muscles, consisting of a configuration where an electrolyte membrane is flanked by two active electrodes, have emerged as transformative components in the field soft robotics. Despite this, current actuation performance falls short for many practical applications, because most existing electrode materials exhibit limitations terms their properties. Here, multifunctional material reported electro‐ionic muscle, employing triazine framework that incorporates...
This paper presents on the effect of surface roughness characteristics for metallic waveguide in D-Band (110 GHz∼170 GHz) which is a candidate component technology 6G mobile RF communications. D-band components based have been widely used existing wireless communications system. The should be considered due to short wavelengths. Generally, common technologies fabricating waveguides include 3D printing, CNC machining, etc. Each fabrication method basically provides specifications such...
Abstract Smart wearable tactile systems, designed to deliver different types of touch feedback on human skin, can significantly improve engagement through diverse actuation patterns in virtual or augmented reality environments. Here, a perpendicularly nested auxetic haptic interface is reported for orthotropically decoupled multimodal (WHOA), capable producing modes with 3D sensory perception. WHOA incorporates shape memory alloy wires that are intricately knotted into an structure oriented...
This letter proposes an efficient uplink scheduling algorithm for the voice over Internet protocol (VoIP) service with variable frame-duration according to activity in IEEE 802.16e/m systems. The proposed dynamically changes grant-interval save bandwidth, and it uses random access scheme when from silent-period talk-spurt. Numerical results show that can increase VoIP capacity by 26 percent compared conventional extended real-time polling (ertPS).
