Special Issue Information

Dear Colleagues,

Mechanical sensing devices in the microelectromechanical system (MEMS) field have been studied and developed over the past few decades. One of the most common MEMS mechanical sensing devices is a pressure sensor that includes the application of small microphones. Accelerators and Coriolis vibratory gyroscopes are famous MEMS mechanical sensing devices because these detects the target physical quantity via their mechanical deformation. In recent years, tactile sensors, including multi-axis force sensors and flexible sensor sheets, have been further studied as applicable to robots. There are also many researches that measure physical quantity such as temperature or chemical quantities as mechanical deformations. The sensing elements of these sensors, a piezoresistive, piezoelectric, and capacitive element, have been developed to realize sufficiently sensitive measurements. In the present IoT age, MEMS mechanical sensing devices are one of the most suitable devices to monitor physical phenomena, because of their size, power consumption, and compatibility for communication devices. Accordingly, this Special Issue seeks to showcase research papers, and review articles that focus on novel developments in MEMS mechanical sensing devices, and their use for various applications.

Capacitive MEMS accelerometers have a high thermal sensitivity that drifts the output when subjected to changes in temperature. To improve their performance in applications with thermal variations, it is necessary to compensate for these effects. These drifts can be compensated using a lightweight algorithm by knowing the characteristic thermal parameters of the accelerometer (Temperature Drift of Bias and Temperature Drift of Scale Factor). These parameters vary in each accelerometer and axis, making an individual calibration necessary. In this work, a simple and fast calibration method that allows the characteristic parameters of the three axes to be obtained simultaneously through a single test is proposed. This method is based on the study of two specific orientations, each at two temperatures. By means of the suitable selection of the orientations and the temperature points, the data obtained can be extrapolated to the entire working range of the accelerometer. Only a mechanical anchor and a heat source are required to perform the calibration. This technique can be scaled to calibrate multiple accelerometers simultaneously. A lightweight algorithm is used to analyze the test data and obtain the compensation parameters. This algorithm stores only the most relevant data, reducing memory and computing power requirements. This allows it to be run in real time on a low-cost microcontroller during testing to obtain compensation parameters immediately. This method is aimed at mass factory calibration, where individual calibration with traditional methods may not be an adequate option. The proposed method has been compared with a traditional calibration using a six tests in orthogonal directions and a thermal chamber with a relative error difference of 0.3%. Full article

This paper presents the design and optimization of a novel MEMS tuning fork gyroscope microstructure. In order to improve the mechanical sensitivity of the gyroscope, much research has been carried out in areas such as mode matching, improving the quality factor, etc. This paper focuses on the analysis of mode shape, and effectively optimizes the decoupling structure and size of the gyroscope. In terms of structural design, the vibration performance of the proposed structure was compared with other typical structures. It was found that slotting in the middle of the base improved the transmission efficiency of Coriolis vibration, and opening arc slots between the tines reduced the working modal order and frequency. In terms of size optimization, the Taguchi method was used to optimize the relevant feature sizes of the gyroscope. Compared with the initial structure, the transmission efficiency of Coriolis vibration of the optimized gyroscope was improved by about 18%, and the working modal frequency was reduced by about 2.7 kHz. Improvement of these two indicators will further improve the mechanical sensitivity of the gyroscope. Full article
