This article introduces a new idea for a micro vacuum sensor. The measuring principle of the sensor is to measure the electrical conductivity of the residual gas in a vacuum chamber. The conductivity is measured between two electrodes that are only 300 nm apart. It has been shown that this type of sensor allows vacuum pressure measurement from atmospheric pressure to high vacuum at very low voltages.

In the presented paper, authors introduced examples of continuous wavelet analysis of load spectra recorded with MEMS gyroscopes during the flight testing. The analysis could be applied for aeroplane load analysis during the flight based on data from simple recorder unit. The other potential application of this method would be academic education. The courses of data analysis, handling qualities or flight testing seem to be still uncommon in aerospace engineering studies.

This paper presents a new wearable gesture interface which is intuitive, fast, accurate, and convenient with MEMS sensors and ZigBee independent of cameras, sensor bars, and surfaces in a broader interactive range. This kind of spatial interaction tool can help more people to express anything through gesture movement. Current gesture interaction mainly works on recognition, while our product applies novel and systematic calculation and realizes more flexible and accurate gesture interaction.
