Abstract Pulse wave carries comprehensive information regarding the human cardiovascular system (CS), which is essential for directly capturing CS parameters. More importantly, cuffless blood pressure (BP) one of most critical markers in CS. Accurately measuring BP via pulse continuous and noninvasive diagnosis a disease associated with hypertension remains challenge highly desirable. Here, flexible weaving constructed self‐powered sensor (WCSPS) reported measurement manner. The WCSPS holds...
Shale gas exploration and development have taken significant strides in the relatively straightforward intra-basin stability zone weak deformation of marine shale Sichuan Basin, South China. In addition, extra-basin strong tectonic modification zones been actively explored. However, results limited, which reveals complexity formation preservation conditions context multi-scale geological processes. These a impact on content, while it has difficult to figure out how modifies reservoir...
Vibration, widely existing in an ambient environment with a variety of forms and wide-range scales, recently becomes attractive target for energy harvesting. However, its time-varying directions frequencies render lack effective technology to scavenge it. Here, we report rationally designed nonlinear magnetoelectric generator broadband multi-directional vibration By using stabilized three-dimensional (3D) magnetic interaction spring force, the device working bandwidth was largely broadened,...
Abstract Traditional gyrocompasses, while capable of providing autonomous directional guidance and path correction, face limitations in widespread applications due to their large size, making them unsuitable for compact devices. Microelectromechanical system (MEMS) gyrocompasses offer a promising alternative miniaturization. However, current MEMS require the integration motor rotation modulation technology achieve high-precision north-finding, whereas conventional motors previous research...
As a key parameter affecting shale gas accumulation, the physical characteristics of reservoir are greatly affected by tectonic stress transformation and deformation, which not only affects occurrence state gas, but also determines evaluation exploration prospect resource potential changing migration enrichment gas. In this study, samples were collected from two different faults based on distance each fault. Comparative analysis micro/nanopore structural properties these was carried out...
Abstract Phase-change material (PCM) is widely used in thermal management due to their unique behavior. However, related research rectifier mainly focused on exploring the principles at fundamental device level, which results a gap real applications. Here, we propose controllable rectification design towards building applications through direct adhesion of composite (TRM) based PCM and reduced graphene oxide (rGO) aerogel ordinary concrete walls (CWs). The evaluated detail by combining...
Piezoelectric micromechanical actuators are featured with a low driving voltage, fast response and large-range output, which make them desirable for applications of long-term drift error self-calibration in microelectromechanical systems (MEMS) inertial measurement units. A vibration platform supported by four folded beams excited 32 partitioned electrodes based on PZT film is presented this paper. PZT-silicon insulator wafer-level MEMS process packaging technique conducted the manufacture...
