In recent years, conventional rigid and planar sensor devices are gradually substituted by flexible and stretchable alternatives. This paradigm shift has paved the way to entirely new applications, particularly in the field of personalized health monitoring or environmental sensing. ... En savoir plus

Nondestructive inspection (NDI) of damages (e.g., imperfect or degraded bonding lines) or the remaining strength of adhesively bonded lap joints is critical for the operational safety of aircrafts and vehicles. It remains a challenge to use the conventional NDI to quantitatively infer ... En savoir plus

Field-effect transistors (FETs) exhibit favourable characteristics for biological and chemical sensing applications, including multi-parameter response, tunable sensitivity, and inherent amplification [1], [2]. As sensors, FETs employ their gate or active channel as a sensing area, where ... En savoir plus

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 ... En savoir plus

Biomemebranes are characterized by several elastic parameters that appropriately describe the energetics of their deformation under thermal fluctuations [1]. When their structure is quasi-two-dimensional (namely lipid bilayer 4-5 nm thick), several recent studies [1,2] showed that their ... En savoir plus

In collaboration with STMicroelectronics, UNIFI employed advanced multiphysics simulations to optimize the electroplating processes used in chip manufacturing. This project focused on enhancing the uniformity and quality of copper layers deposited on microchips, which are integral ... En savoir plus

The present work explores the integration of guided mode resonance (GMR) structures and topological photonics, characterized by the presence of Jackiw-Rebbi (J-R) solution. The developed surface enhanced GMR structure may serve as a platform for refractive index sensing across various ... En savoir plus

In this work, a 2.8x0.22 μm^2 silicon strip waveguide (n = 3.43 @4.234 μm) on a silica substrate (n = 1.38 @4.234 μm) and a superstrate with n = 1 was designed and evaluated through 2D (i.e., mode analysis), and 3D (i.e., wave propagation) analysis to strengthen the interaction between ...

Europeans spend between 80% to 90% of their time indoors, for example at home, school, office, and other public buildings. Besides, due to energy-saving measures in buildings, natural ventilation is reduced leading to the accumulation of indoor air pollutants. Consequently, indoor air ... En savoir plus
