In this paper, we propose a novel pulse acquisition system based on MEMS technology, where finger-end pressure and micro-sensor array applications are combined to achieve a high degree of integration of multi-channel information at the pulse acquisition end. A static stress analysis model for blood vessels based on the finite element method is proposed, which is used to investigate the effects of the modulus of elasticity of the vessel wall, and the inner diameter of the vessel on the outward pressure. The blood flow patterns of people with different blood pressures were simulated by varying the pressure intensity of the vessel wall. And the accuracy of the model was verified by collecting pulse waves of hypertensive patients by the designed pulse information acquisition system. This study is expected to enable non-invasive and low medical cost preliminary vascular lesion diagnosis through the detection of pulse. © 2024 IEEE.

The spontaneous growth of tin whiskers has resisted interpretation for more than 70 years. Herein, tin whisker growth behaviours on Ti2SnC bulks cold-pressed under different pressures were studied. It was found that higher whisker growth propensity is reached when Ti2SnC cold-pressed under higher pressure. Several thicker whiskers with diameter more than 3 μm were observed on the samples formed under higher pressure, while the diameter of more than 50% whiskers ranges from 0.5 μm to 1.5 μm for all of the samples. An atomic motion mechanism, in which the element source supplying Sn whisker growth diffuse through the Sn atom layer in Ti2SnC lattice, and the interaction between Ti2SnC and Sn is considered to be the fundamental factor initiating the Sn whisker growth, was employed to understand the phenomena. The findings herein provide new clues to understand the tin whisker growth behaviors and modulable metal whisker fabrication. © Published under licence by IOP Publishing Ltd.
