Abstract Elastico‐mechanoluminescence technology has shown significant application prospects in stress sensing, artificial skin, remote interaction, and other research areas. Its progress mainly lies realizing visualization 2D or even 3D stress‐sensing effects using a passive sensing mode. However, the widespread promotion of mechanoluminescence (ML) is hindered by issues such as high strain thresholds single mode based on luminous intensity. In this study, highly efficient green‐emitting ML...
Abstract Mechanical quenching (MQ) represents a distinctive mechano‐optical response, in which the afterglow intensity is quenched under applied mechanical stress. Compared with mechanoluminescent (ML) materials, research on physical mechanism and sensing application of MQ materials still insufficient. Moreover, existing typically respond only to dynamic stress, while ML are unable exhibit luminescence static restricting their utility stress‐sensing applications. In this work,...
Abstract As urban rail transit construction advances with information technology, modernization, information, and intelligence have become the direction of development. A growing number cloud platforms are being developed for in areas. However, increasing scale platforms, coupled deployment safety applications on platform, present a huge challenge to reliability.One key components is Automatic Train Supervision (ATS). The failure ATS service would result less punctual trains decreased...
BAW (Bulk Acoustic Wave) filters, commonly implemented in ladder or lattice topologies, have been widely adopted as RF filters for high frequencies. However, the bandwidth of these filter topologies is limited by effective electromechanical coupling coefficient resonators, which decided piezoelectric material and difficult to increase. In this study, a new topology proposed construct N77 full band with steep skirts can coexist N79 hybrid integrating resonators IPD (Integrated Passive Device)...
Abstract Objective. Recent studies have shown that integrating inertial measurement unit (IMU) signals with surface electromyographic (sEMG) can greatly improve hand gesture recognition (HGR) performance in applications such as prosthetic control and rehabilitation training. However, current deep learning models for multimodal HGR encounter difficulties invasive modal fusion, complex feature extraction from heterogeneous signals, limited inter-subject model generalization. To address these...
Background Sleep disorders are prevalent among patients with schizophrenia and associated several negative consequences. Although, researchers have recently suggested that sleep a close correlation alexithymia, also has strong there been few studies on the relationships between schizophrenia, alexithymia. Therefore, this study aimed to explore psychiatric symptoms, alexithymia problems in so as provide reference for clinical treatment of comorbidity. Methods In total, 977 were recruited...
A fully integrated supply voltage and temperature variation-tolerant relaxation oscillator for biomedical systems has been presented.
