Condenser microphones will have an electrical output for any displacement of the membrane relative to the back plate, which is usually bound to the microphone housing. For the typical use case, a pressure input will create a pressure difference across the membrane, which causes a ... Read More
An "electroacoustic absorber" is a loudspeaker, used as an absorber of sound, which acoustic impedance can be varied by electrical means. This can be achieved either by plugging passive shunt electric networks at the loudspeaker terminals ("shunt loudspeakers") or by feeding back the ... Read More
Electrical Stimulation is widely used today for Deep Brain Stimulation treatments and retinal prostheses. The Electrical Double Layer formed at the interface between the electrode surface and the extracellular medium is considered thru the linear Helmholtz model and the nonlinear more ... Read More
This work reports the application of topology optimization for the design of two types of metallic antennas that are very different from each other: a leaky-wave antenna (LWA) radiating at broadside, and an epidermal patch antenna, optimized to favor radiation coupling into the human ... Read More
Foundation scour is a major cause of bridge collapse worldwide (e.g., Kirby et al., 2015). Indeed, several studies have demonstrated its detrimental effects on the soil-structure system, both in terms of the foundation capacity and stiffness (e.g., Foti et al., 2023). Furthermore, the ... Read More
In the context of climate change mitigation, hydrogen represents a promising and versatile energy vector. Water electrolysis powered by renewable energy offers a sustainable method for hydrogen production, with efficiency gains achievable at the higher operating temperatures of Solid ... Read More
压电材料在受到机械应力时会产生电压，这种性质使压电材料在声波传感器领域具有广泛应用。湿度的测量和把控广泛地应用于粮食贮存、气象预报与加工以及国防建设等各个领域。当今社会对各种成本低、性能优异的湿度传感器的需求正在日益上升。石英晶体微天平（QCM）具有高灵敏度、无需物理接触、体积小、易于集成等特点，通过在石英晶体微天平表面覆盖一层能够响应水分子的材料，可以监测环境中的湿度。这种材料能够吸收和解吸水分，从而改变石英晶体的质量，进而影响其共振频率。通过检测这一频率的变化，我们可以准确获取周围的相对湿度。本研究利用有限元软件COMSOL的多物理场耦合功能 ... Read More
Particle In Cell (PIC) simulation tool for the simulation of 2.45GHz ECR ion source was developed tanks to Comsol Multiphysics RF module capability to compute electromagnetic field propagation imposing a tensorial permittivity with real and complex parts. A tensorial description is ... Read More
Accurate measurement of electrode loads is crucial for the optimal operation of a large 3-phase electric melting furnace. Generally, measurements are made by combining electrode current and voltage drop between the top of the electrodes and the core of the furnace. For this purpose, the ... Read More
The contamination of food products with low water contents is a safety issue that cannot be disregarded. Despite their low water activity, they are indeed susceptible to infection by micro-organisms that are highly resistant to heat. In this case, conventional pasteurisation techniques ... Read More
