An Edible Chitosan‐Based Acoustic Sensor for Sound‐Responsive Actuation in Edible Robots
Advanced Functional Materials, EarlyView.This study introduces an edible acoustic sensor for robotic food and edible robotics. Built from a chitosan piezoelectric film between gold electrodes, the sensor enables acoustic communication through ON/OFF keying. Integrated into an edible robot with pneumatically actuated arms and neck, it responds to high‐frequency tones.

Fault Location in High Voltage Transmission Lines Using Resistance, Reactance and Impedance
Journal of Advanced Engineering and Computation, 2018 This paper presents two methods for on-line computation of dynamic fault location in HV transmission lines using three means; resistance, reactance and impedance. These methods can be used for dynamic distance protection of the transmission line.

Charge‐Tunable Coacervate Micelles for Separator Engineering in Lithium‐Sulfur Batteries
Advanced Functional Materials, EarlyView.A separator engineering strategy based on charge‐tunable complex coacervate core micelles (C3Ms) is presented to form an ion‐selective layer regulating polysulfide transport in Li–S batteries. The micelles enable uniform adsorption onto commercial polypropylene separators and infiltration throughout the internal pore network, suppressing polysulfide ...

Известия высших учебных заведений: Проблемы энергетикиRelevance. Rural 0.4 kV electrical networks are characterized by low protection against emergency currents, especially remote single-phase short circuits, which have values comparable to load currents. The protective devices at the beginning of the power

Capacitively-Loaded Feed Line to Improve mm-Wave and Sub-6 GHz Antenna Co-Existence
IEEE Access, 2020 The co-existence of millimeter-wave (mm-wave) and sub-6GHz antennas in a smartphone presents many performance-limiting aspects. When both antennas are attached to the metal frame, the feed lines of the mm-wave antennas might short-circuit the sub-6GHz ...
