The sensor comprises an insulating substrate, an MTJ array arranged on the insulating substrate and composed of MXN MTJ units arranged at intervals; connecting electrodes used for connecting the two adjacent MTJ units located in the same row in the MTJ array in series and connecting a row of the MTJ units and the next row of the MTJ units in the MTJ array in series, and adjusting electrodes led out from the multiple connecting electrodes. The adjacent MTJ units in each row in the array and the adjacent rows of the MTJ units are connected in series throughthe connecting electrodes, and the adjusting electrodes are led out from one or more connecting electrodes; the number of the MTJ units connected in series can be selected by selecting different adjusting electrodes as input ends and output ends; and the resistance value can be adjusted through short circuiting of the certain adjusting electrodes, so that the zero point adjustment of a circuit canbe realized.

The invention relates to a preparation method for a micropattern film with a selective stimulation recovery function, aiming at solving the technical problem that the application of the micropattern is quite limited as the recovery position of a conventional shape memory micropattern is not selective. The preparation method comprises a first step of isolating a silicon wafer; a second step of dripping a shape memory polymer and curing; and a third step of stripping and flattening. The preparation method has the advantages that the shape memory micropattern film with the selective stimulation recovery function prepared with the sticky and thick shape memory polymer as a matrix can be stimulated by multiple manners, and has the characteristic that only the micropattern of a corresponding position can recover under different stimulation conditions. Through adoption of the preparation method, the controllability and selectivity of recovery positions are realized, and the preparation method is simple, has strong operability, and is conducive to application of the shape memory polymer material in multiple fields like aerospace, optical zoom, password transmission, sensors and so on.

The invention relates to a preparation method of a Co-based catalyst and application of the Co-based catalyst in eugenol conversion. The Co-based catalyst comprises a CoAl-O, CoAl-S or CoAlMo-S catalyst. CoAl hydrotalcite is taken as a precursor, and the Co-based catalyst in different existence forms, including cobalt oxide, cobalt sulfide and a Mo-doped cobalt molybdenum sulfide catalyst, is prepared, so that selectivity of catalyst activity is realized. The Co-based catalyst, taking activity of CoAlMo-S as an example, has the hydrodeoxygenation capability much higher than that of a commercially purchased CoMo / Al2O3 sulfide catalyst in catalytic conversion of a lignin model compound eugenol.
