A stretchable pressure sensor can provide highly sensitive and strain-unperturbed measurement to pressures on deformed skins.
A flexible pressure sensor array provides more information than a single as electronic skin, and independently definable sensitivities of sensing pixels enable accurate measurements. However, the reported approaches, either changing mold for dielectric layer or tuning properties, overcomplicate manufacturing process devices. Here, we present with photo-patterned sensitivity, which is realized through synergistic creation photo-defined mechanical properties interfacial capacitive mechanism....
Flexible piezoresistive pressure sensors have great potential in wearable electronics due to their simple structure, low cost, and ease of fabrication. Porous polymer materials, with highly deformable internal pores, effectively expand the sensing range. However, a single-sized pore structure struggles achieve both high sensitivity broad range simultaneously. In this study, PDMS-based flexible sensor bilayer porous (BLPS) was successfully fabricated using clamping compression sacrificial...

Sorting particles or cells of specific sizes in complex systems has long been a focus many researchers. Acoustic surface waves, which generate acoustic radiation forces on and, thus, influence their motion, are commonly used for the non-destructive separation sizes. In previous studies, frequency wave generation limited by interdigitated transducer (IDT). To extend effective operating range IDT, slanted-finger (SFIT) with wide path and multiple frequencies was designed. Compared traditional...
Flexible pressure sensors face the dual challenges of weak signal extraction and environmental noise suppression in wearable electronics human-machine interfaces.

Graph convolutional networks (GCNs) have achieved outstanding performances on skeleton-based action recognition. However, several problems remain in existing GCN-based methods, and the spatial-temporal features are not discriminative enough. Temporal convolution with one fixed kernel cannot obtain more temporal for different actions. Besides, only a single-scale feature is used classification, which ignores multilevel information. In this article, we propose novel multi-scale multi-stream...
