Recent Advances in Flexible Nanogenerators for Microphone and Loudspeaker Applications

ACS Applied Electronic Materials (2023)

Dongfang Yang Longlong Zhang Licheng Wang Kai Wang

Nowadays, ferroelectret nanogenerators have been proposed as a possible alternative method for kinetic energy collection. We describe the component's inherent features, which enable the bidirectional transfer of energy between the electrical and mechanical fields, expanding its potential application in wearable electronics beyond power production. Such electromechanical linkage gives the device dual-functional transducing features, demonstrating its application as a small, portable, and self-powered loudspeaker or microphone patch. This coupling, together with the flexibility and thin-film-like shape, gives the device these characteristics. For three alternative configurations, the sound pressure level is assessed in the spatial and frequency domains to ascertain the device's functionality and usability. Also, dependencies of sound pressure levels (SPLs) generated by a FENG due to an AC voltage stimulus, surface area, geometric shape, and addition of layers are presented here.

Using neural network to predict reliability of lithography machine

Ruiyao Yang Longlong Zhang Wei Cai Yu Liu Hong‐Zhong Huang

Dual-stage lithography machine is still in the prototype development stage and it is meaningful to study its reliability. Since this kind of machine is very stable, there are not enough failure data and adequate available samples for us during the analysis process. Considering these factors, this paper will take advantage of similar equipment method and neural network to predict the reliability of lithography machine. An example of lithography machine was given to verify this method. The result can guide designers to improve their design process.

The Application Study on Solar Photovoltaic Technology in the Ocean Park Design

Jingwen Yuan Longlong Zhang Chul Soo Kim

First of all, the marine ocean design focuses on practical value, then satisfies the design and construction of human landscape and lastly complies with environmental concerns. This paper considers some inherent forms like public buildings with sustainable solar installations in harmony with the urban landscape, puts forward the basic principles of reducing decorative elements, improving structural safety and efficiency, and presents the details the theory of color, color and material. This reflects the unique form of the building and reduces the decorative elements so that the form is integrated into the building. In the installation of the photovoltaic power system, this paper offers a design direction, emphasizing the relization of harmony through integrated planning with public buildings. The design guide proposed in this paper is expected to be the basic format to guide the design of efficient photovoltaic power generation system in the marine park.

Bolted and Seeded-Geomat Protection System to Reduce the Erosion Rate of High and Steep Slopes

Wei Shi Tong Liu Xiaohui Sun Longlong Zhang Tao Lu

The excavation of mountains due to the construction of infrastructures not only deteriorates the ecological environment but also causes severe secondary disasters, such as soil erosion, landslide, and debris flow. Therefore, the reinforcement and ecological protection of the high-steep slopes are important and attract more attentions from researchers. In this study, the bolted and seeded-geomat protection (BSGP) technology, which combines rock bolts with geomats which have seeding, was applied to stabilize an unstable high-steep slope. The erosion rate of the surface soil on the slope was analyzed based on the field-collected samples and laboratory test data. The influence of the slope angle, geomat type, vegetation type, and bolt spacing on the erosion rate under different rainfall intensities were investigated by orthogonal tests. The results indicate that the slope angle controlled the erosion rate of the slope and the geomat had more effects on the decrease of the erosion rate as compared with other variables.

Research on the type of load of accessing to microgrid based on reliability

Advances in computer science research (2015)

Longlong Zhang Ming Sun

The microgrid provides a new form of Distributed Generation accessed to distribution network .With the development and application of microgrid technologies, its ability to meet the power supply reliability needs of loads in microgrid has become a problem that should be solved.To this end, the paper divides the loads according to the power supply reliability, builds a microgrid model constituting of wind/photovoltaic power /independent storage power, and investigates the reliability evaluation method based on Monte Carlo simulation.By an example of IEEE-RBTS system, the paper compares the reliability level of loads in normal distribution network with those in the microgrid, finally draws the conclusion, the third-class load is the most suitable load accessed to microgrid.
