“…IR-coupled ultrasonic transducers operating as either transmitters, receivers or transceivers have found many applications in fields such as robotics, automotive, communication, haptics, particle manipulation, flow measurement, and non-destructive testing and evaluation [1][2][3][4][5][6][7][8][9][10][11][12]. The parameters of an ultrasonic measurement system such as transduction efficiency, operating frequency, bandwidth, directivity, operating voltage (or current), and power consumption are all underpinned by the performance of the ultrasonic transducers.…”

“…The sensitivities for CO 2 and SO 2 were observed to be 8 and 20 Hz/ppm, respectively. These values represent higher sensitivities compared to other reported CMUT sensors [41]. The increased sensitivity to SO 2 likely results from its ability to form a stronger and irreversible hydrogen bond-type interaction with the polymer during sensing.…”

Microelectromechanical system (MEMS)-based mass sensors are proposed as potential candidates for highly sensitive chemical and gas detection applications owing to their miniaturized structure, low power consumption, and ease of integration with readout circuits. This paper presents a new approach in developing micromachined mass sensors based on capacitive and piezoelectric transducer configurations for use in low concentration level gas detection in a complex environment. These micromachined sensors operate based on a shift in their center resonant frequencies. This shift is caused by a change in the sensor’s effective mass when exposed to the target gas molecules, which is then correlated to the gas concentration level. In this work, capacitive and piezoelectric-based micromachined sensors are investigated and their principle of operation, device structures and configurations, critical design parameters and their candidate fabrication techniques are discussed in detail.

“…The technology does not involve thermal effects, which can effectively protect the activity of thermally unstable active substances, in addition, the technology is simple and economical to operate. Due to these advantages, this technology has been widely used in biomedicine, food packaging, sensors and other fields 15–19 . Because there is lack of case of applying coaxial electrospinning technology to the field of insect repellents, this study provides a relatively novel technical route for the research and development of mosquito repellent products.…”

Nepeta essential oil (NEO) is considered to have good mosquito repellent properties, the poor stability of which limits the application. This work was aimed at using coaxial electrospinning technology to wrap NEO into Polylactic acid (PLA) fibers to extend the service life of NEO. Under the best test conditions, NEO load capacity (LC) and encapsulation efficiency (EE) is (20.20 ± 0.35%) and (84.18 ± 1.46%), respectively. According to morphology analysis, the concentration of PLA solution and the flow rate of NEO will affect the morphology and properties of the fibers, and the minimum average diameter of the obtained fibers is 740 nm. Release test indicates that using coaxial electrospinning technology can significantly slow down the NEO release rate, in the mosquito avoidance test, the coaxial fiber mat maintained about 80% mosquito repellent rate within 72 h, which is superior to the commercially available N,N‐diethyl‐3‐methylbenzamide (DEET) repellent, indicating its potential in the field of mosquito repellent.
