Abstract: The present application discloses a strain sensing film, a pressure sensor, and a strain sensing system; the strain sensing film includes a semiconductor film, and by arranging a temperature sensor in the semiconductor film, the sensitivity of the strain sensing film is adjusted according to an effective gauge factor obtained from a calibration test and a correlation table reflecting a correlation between an effective gauge factor and a temperature, a better effective gauge factor compensation is achieved, a high sensitivity of the strain gauge of the semiconductor film can be fully utilized. The strain sensing film can be widely used in application scenarios that need to measure local strain or strain variation, force or force variation, pressure or pressure change, displacement, deformation, bending, or bending deformation.

Abstract: The present application provides a strain sensing film, a pressure sensor, and a hybrid strain sensing system. The strain sensing film includes a semiconductor thin-film, at least two resistors are disposed on the semiconductor thin-film, one resistor has a different response to a strain with respect to at least another resistor, thereby enhancing resistance to external environmental disturbances and improving the accuracy of pressure measurements.

Abstract: The present invention relates to the field of fullerene application, and in particular to an application of fullerene and a derivative thereof in regulating intestinal flora. The fullerene and the derivative thereof may increase beneficial bacteria, decrease harmful bacteria and increase the abundance of intestinal flora when used for regulating intestinal flora, which is thus capable of relieving or treating human diseases (including gastrointestinal diseases, neurodegenerative diseases, metabolic diseases, sleep disorders, inflammation, tumors) and enhancing human immunity, improving animal physiques, regulating animal intestinal tracts, preventing or treating animal diseases, or promoting animal growth with great application prospect.

Abstract: A fullerene arc source and a fullerene production apparatus comprising the arc source. More than one independent arc source (2) is mounted in a vacuum furnace (1). Each arc source (2) comprises an anode (21) and a cathode trigger (23). The anode (21) is in contact with the cathode trigger (23) to generate an arc and a triggering end of a positive electrode is vaporized to produce a mixture comprising the fullerene. The multiple arc source (2) in the vacuum furnace (1) simultaneously work to industrially produce the fullerene in a mass manner.
