Summary: This paper presents a design of a multi-axis tactile force sensor that utilizes the fringe effect of an electric field between stationary patterned electrodes. The unique electrode configuration enhances the sensitivity and allows for decoupling of normal, shear, and angular shear forces. The sensor is made using low-cost rapid prototyping techniques and is suitable for force feedback in minimally invasive robotic surgery due to its linear response, repeatability, low hysteresis error, thermal stability, and robustness to environmental interferences.

Summary: By taking advantage of magnetic proximity effect, we observed anomalous Hall effect in CuCrP2S6/few-layer graphene bilayer structures, with a significantly smaller saturation field compared to bulk CuCrP2S6. This smaller saturation field is believed to result from charge transfer between CuCrP2S6 and few-layer graphene. Density functional theory calculations further revealed exchange splitting in graphene due to the coupling between CuCrP2S6 and few-layer graphene. Our work sheds light on the magnetism of individual 2D CuCrP2S6 and paves the way for novel magnetoelectric coupling in emerging 2D heterostructures.

Summary: Flexible capacitive humidity sensors show potential for low-cost, wearable, and radio frequency identification applications, but their nonlinear response poses a challenge. The linearity of humidity response can be controlled by adjusting surface water wettability and operating frequency of the sensor, with the mechanism explained by surface water condensation. Experimental and simulation results indicate that the increase in sensor capacitance is greatly influenced by the geometric pattern and electrical permittivity of surface water droplets.

Summary: A grating-assisted hybrid plasmonic slot resonator is proposed to enhance surface-enhanced Raman scattering (SERS) detection on a chip. By introducing a dielectric Bragg grating and a gold baffle into the hybrid plasmonic slot waveguide as two mirrors, a plasmonic-dielectric cavity is formed, in which the constructive interference of the input pump light greatly enhances the electric field. The grating reflects the wasted pump light for reverse secondary coupling and acts as a built-in notch filter for filtering out pump light from Raman scattered light simultaneously, improving the coupling efficiency and achieving a compact and miniaturized SERS sensor.

Summary: This paper discusses the development and analysis of capacitive proximity sensors (CPSs) using SiO2 nanoparticles and NaCl. The sensors were designed with a simple electrode structure to focus on the sensing layer and the impact of NaCl. Experimental results showed that the diffusion of charge carriers dominates the sensing mechanism due to chemical reactions between NaCl and SiO2 nanoparticles. The presence of NaCl in the sensing layer enhances the proximity sensing capabilities, with maximum sensitivities achieved with 25% and 50% NaCl concentrations.

Summary: The QCM can detect both the mechanical and electrical properties of liquid, including density, viscosity, dielectric constant, and conductivity. Previous research has mainly focused on the conductive property using relative values, which is insufficient to fully reflect the QCM response to liquid electrical properties. In this study, the effect of electrical field scattering on the QCM response to liquid electrical properties was investigated, along with the coupling between mechanical, dielectric, and conductive properties. The results showed that electrical field scattering significantly affects the QCM sensitivity to the dielectric property of liquid, and there is a coupling between dielectric and conductive properties at low conductivity.

Summary: With the development of Lab on a chip technology, fluid management using dispersed droplets has become an important approach. Electrowetting on dielectric (EWOD) is one method for droplet actuation, but it requires prior definition of droplet positions. Optoelectrowetting (OEW) goes further by allowing changes in electrical parameters through impinging light spots, without the need for predefined droplet positions. This study re-evaluates the key parameters of OEW and explores their effects on droplet actuation using numerical optimization methods.
