Summary: Surface crack detection and sizing is crucial in the manufacturing and maintenance of aircraft engines and metal parts. The non-contact and non-intrusive technique based on laser-stimulated lock-in thermography (LLT) has gained attention in the aerospace industry. A reconfigurable LLT system is proposed for three-dimensional surface crack detection in metal alloys. It allows for quick localization and accurate measurement of crack dimensions, and can also be applied to non-destructive defect detection in other materials.

Summary: The use of plasmonic nanoparticles in biological applications has increased over the past two decades due to their ability to generate heat when exposed to light. Lock-in thermography can efficiently measure the heat produced by these nanoparticles, and a mathematical model based on energy balance using Mie theory can quantitatively predict the heat generation by gold nanoparticles in different concentrations and wavelengths. The model shows a linear increase in temperature response with gold concentration and independence from particle size.

Summary: This paper introduces the use of eddy current thermography to detect metal in wood materials and proposes the TSR algorithm to address the low resolution of metal detection. The algorithm significantly enhances the contrast between metal and surrounding areas, effectively identifies different quantities of metal, and accurately realizes metal position. Experimental results demonstrate that this technology can quickly detect metal in wood materials, improving efficiency and accuracy by allowing intuitive observation of metal size and quantity through thermal images.

Summary: This study investigates the latent degradation of SiC MOSFETs under single-pulse avalanche conditions using Unclamped Inductive Switching (UIS) tests. It is found that the devices fail abruptly without any parametric shift even after dissipating more than 90% of the maximum avalanche energy. The failure is determined to be a result of reaching the critical temperature. By introducing corrections and a more accurate temperature model, a critical temperature of around 1200 K is derived. The main mechanism of avalanche failure in the rated current region is considered to be the fusion of metallization, although the turning-on of parasitic BJT can also accelerate the failure under high currents.

Summary: To solve the application limitations of conventional detectors caused by discrete phase distribution of high-order APSK signals and the degradation of detection performance, a carrier synchronization lock detector based on weighted detection statistics is proposed. The proposed detector calculates a weighted factor based on the amplitude difference of the signal on the APSK constellation to adjust the weight of detection statistics for different rings. The detector solves the detection performance degradation problem of the Linn detector caused by uneven phase distribution and improves the detection performance.

Summary: A novel solution for off-chip electrothermal studies in power devices at die level and short timescales is proposed in this study. The proposed method involves acquiring a sequence of thermal images using an infrared camera and reconstructing the time evolution of the device thermal map using Fourier series. The results demonstrate that the proposed strategy significantly improves the thermal and time resolution, overcoming the limitations of the camera's frame rate and noise resolution.

Summary: This study utilized a fiber-optic-based sensor network to monitor the liquid resin infusion process. The test object was a panel consisting of a skin and four stringers, which were equipped with temperature and resin arrival sensors. By using Fiber Bragg Gratings (FBGs) as temperature sensors and modified fiber optic probes to detect resin presence, the system was able to validate an infusion process numerical model and provide insights into the actual resin flow and drying time during the infusion process.

Summary: This study presents a true multimodal pulse wave (PW) sensor that integrates a piezoelectric forcecardiography (FCG) sensor and a photoplethysmography (PPG) sensor for simultaneous mechanical-optical measurements of PWs from the same body site. The preliminary results show a delay between the PWs recorded by the PPG and FCG sensors, but high cross-correlation indices were observed. Further investigation is needed to understand the physical origin of the delay and validate the results in a larger subject cohort. This research paves the way for the development of wearable, integrated sensors and sensor fusion approaches to improve PW monitoring.

Summary: This paper proposes a lumped-charge model for IEGT single chip, considering the effect of carrier injection enhancement in the emitter. The parasitic inductance of the parallel branches in PP-IEGT is extracted using Ansys simulation, and the validity of Ansys simulation is verified. Furthermore, the switching inconsistency is evaluated by combining the electrical model and the effect of mutual inductance, and it is found that mutual inductance is an important factor influencing electrical parameter distribution.

Summary: Using SEM/EDX analysis, microscale fracture at the bond-pad is detected during the wedge bonding process of Cu wire to a Cu or Al substrate. It is observed that the fracture of the bond leads to the formation of a bulge on the wire and a cavity in the substrate, causing fracture in the original substrate. 3D optical profiler reveals that the depth, radius, and surface area of the cavity increase with bond time for a constant bond force and power. These metrics are suggested as new factors for optimizing the wedge bonding process. The optimal bonding parameters should maximize the cavity's surface area (related to bond's pull force) while minimizing the cavity's depth relative to the substrate's thickness to avoid substrate damage. Furthermore, Molecular Dynamics simulations propose a potential plastic deformation mechanism for bond-pad damage, suggesting the benefits of using a small-grain-sized substrate, low transducer's vibration amplitude, and high transducer's frequency to minimize the cavity's depth.
