A method which can accurately measure surface pressure under rotating conditions is presented. Based on the calibration for strain type pressure sensor, a curve which shows the functional relationship between sensor output signal and actual pressure under different rotational speed is obtained; and the diaphragm deformation caused by centrifugal force can be neglected by the curve. Thus, the actual pressure can be acquired accurately. The factors which may cause errors on the experiment are analyzed. Moreover, the correctional method for the experimental data is attained.

Millions of smartphones possess relatively accurate pressure sensors and the expectation is that these numbers will grow into the hundreds of millions globally during the next few years. The availability of millions of pressure observations each hour from smartphones has major implications for high-resolution numerical weather prediction. This paper reviews smartphone pressure-sensor technology, describes commercial efforts to collect the data in real time, examines the implications for mesoscale weather prediction, and provides an example of assimilating smartphone pressure observations for a strong convective event over eastern Washington State.

The colonoscopic robot with continuum structure can offer enhanced environmental interaction by deforming to fit environmental constraints. In order to improve its perception ability and avoid perforation and other kickbacks, it is necessary to integrate pressure sensors into colonoscopic robot. A surface pressure sensor for the measure of contact pressure between colonoscopic robot and colon wall is designed. The sensor is made of aluminum and is 15.6mm in diameter and 3mm in width. It consists of external ring, internal ring, connection and two resistance strain gauge. The mechanical structure of the sensor is introduced. The mechanical characteristics is analyzed and simulated by the finite element analysis software ANSYS. The experiment system is built and the data is sampled through Wheatstone bridge. The data fitting is performed based on least squares method with Matlab software. The result shows that the surface pressure sensor has advantages of good linearity and accuracy. This study lays a foundation for the practical application of colonoscopic robot.
