Abstract Flexible and wearable sensors are highly desired for health monitoring, agriculture, sport, indoor positioning systems applications. However, the currently developed wireless sensors, which communicated through radio signals, can only provide limited accuracy often ineffective in underwater conditions. In this paper, a platform based on flexible piezoelectric acoustics is with multiple functions of sensing, communication, positioning. Under high frequency (≈13 MHz) stimulation, Lamb...
Sensitivity of flexible surface acoustic wave (SAW) sensors to ultraviolet (UV) light is enhanced by the application ZnO micro- and nanostructured networks as sensing layers. In this study, influence three-dimensional (3D) tetrapodal microstructured (T-ZnO MNs) spin coated onto Al foil/ZnO piezoelectric film SAW devices on sensor performance under a stimulus UV-light irradiation relative humidity was investigated. The sensitivity increased from −3.03 × 10–6 −5.25 cm2 mW–1 with 3D T-ZnO MNs....
In this paper, we explore the acoustofluidic performance of zinc oxide (ZnO) thin-film surface acoustic wave (SAW) devices fabricated on flexible and bendable thin aluminum (Al) foils/sheets with thicknesses from 50 to 1500 μm. Directional transport fluids along these flexible/bendable surfaces offers potential applications for next generation microfluidic systems, wearable biosensors soft robotic control. Theoretical calculations indicate that bending under strain levels up 3000 με causes a...
Flexible human-machine interfaces show broad prospects for next-generation flexible or wearable electronics compared with their currently available bulky and rigid counterparts. However, to counterparts, most reported devices (e.g., loudspeakers microphones) inferior performance, mainly due the nature of flexibility. Therefore, it is great significance improve performance by developing optimizing new materials, structures design methodologies. In this paper, a acoustic platform based on zinc...
Excessive exposure to airborne particulate matter (PM), especially PM2.5 particles, adversely affects human health. Conventional detection instruments based on light scattering are generally bulky, expensive, and easily affected by particle size composition. Here, we report a low-cost compact one-stop platform integrating three-dimensional (3D) printed virtual impactor with QCM sensor. To reduce eddy airflow impact the side wall improve VI lifetime, computational fluid dynamics simulation is...
Three pre-patterned ZnO nanoribbons in different configurations were studied this paper, including (a) straight uniformly bonded on soft substrates that form sinusoidal buckles, (b) selectively pop-up and (c) serpentine via anchors. The nonlinear dynamics random analysis conducted to obtain the fundamental frequencies evaluate their performance energy harvesting applications. We found buckles overhanging structures are suitable for audio frequency Remarkably, almost unchanged natural upon...
With an increased demand for various cell-based clinical applications and drug discovery, enable technology that can automatically locate pair biological cells from different groups, with high precision throughput, is highly demanded. This paper presents a novel approach to achieving such cell manipulation using controlled holographic optical tweezers system, where robotically functions as special manipulator transfer automatically. The proposed pairing utilizes the concept of concentric...
This paper describes the mechanism of rate-dependent adhesion for a transfer printing system. A cohesive element model accounting viscoelastic effect stamp reveals evolution stress and distributions as peeling velocity increases. Experiments using Si ribbons separating from wafer verify this prediction demonstrate influence on efficiency. The simulations show relaxation time has little efficiency, implies that it can be improved by adjusting modulus.
Timely detection and elimination of surface condensation is crucial for diverse applications in agriculture, automotive, oil gas industries, respiratory monitoring. In this paper, a smart patch based on ZnO/aluminum (∼5 μm/50 μm thick) flexible Lamb wave device has been proposed to detect, prevent, eliminate condensation, which can be realized using both its surfaces. The operated machine-learning algorithm consists data preprocessing (feature selection optimization) model training by random...
