Special Issue Information

Dear Colleagues,

As the size of electronic devices continues to shrink, the design and application of micro- and nano-sized sensors become increasingly more important. Sensors with different types of sensitivity (e.g., thermal, gas, pressure, and humidity) have been utilized in various fields, including among others biomedical science, environmental, and healthcare industries. This Special Issue aims to highlight the recent development and advanced features of micro- and nano-sensors in various applications. There is no limitation on the materials (e.g., nanowires, quantum dots, 2D materials, and other molecular structures), purposes (e.g., pressure, power, speed, thermal, and ray radiation), working principles (e.g., gas/magnetic sensitive, biosensors, and vibration or vacuum sensors), manufacturing methods (e.g., top-down lithography and bottom-up assembly), etc. All information related to micro- and nano-sized sensors is welcomed, but the selected papers must be leading topics with special potential for development in the next decade.

In this paper, multi-physical models of bending characteristics, including the static, dynamic and microwave models, are firstly proposed for the double-clamped beam switch based on flexible substrate. Both simulated and experimental verification have been carried out to prove that the changing regularity of the driving voltage and time of the switch is inversely proportional with the increase in the bending curvature of the flexible substrate. The microwave performance of the switch at the ON state is found to get worse with the increase in the bending curvature. The measured results indicate that when the bending curvature increases from 0 m−1 to 28.6 m−1, the measured driving voltage decreases from 90.0 V to 72.6 V with the error of 5.9% compared with the calculated results. The measured driving time decreases from 52.4 μs to 35.6 μs with the error of 16.7% compared with the calculated results. When the substrate bending curvature increases from 0 m−1 to 28.6 m−1, the measured reflection loss S11 of the switch gradually deteriorates from −27.1 dB to −22.0 dB with the error of 1.3 dB corresponding to the calculated results at 10 GHz. All the simulated and experimental results are consistent with the theoretical calculated results. Full article

Mercury ions (Hg2+) pollution in the water environment can cause serious harm to human health. Trace Hg2+ detection is of vital importance for environmental monitoring. Herein, we report a novel design of Ru-MOFs modified gold microelectrode for Hg2+ determination. Ru-MOFs are synthesized directly by the cathodic method on gold microelectrode, with the covered area accurately controlled. Cathodic synthesized Ru-MOFs show good conductivity and are suitable to be used as the electrode surface material directly. The synergy of the pre-deposition process and the adsorption process of Ru-MOFs can effectively improves the performance of the sensor. The results show good linearity (R2 = 0.996) from 0.1 ppb to 5 ppb, with a high sensitivity of 0.583 μA ppb−1 mm−2. The limit of detection is found to be 0.08 ppb and the test process is within 6 min. Most importantly, the senor has a good anti-interference ability and the recoveries are satisfactory. This miniature electrochemical sensor has the potential for on-site detection of trace mercury in the field. Full article
