Abstract: A titanium sulfide (TiS) nanomaterial and a composite material thereof for wave absorption are disclosed. The TiS nanomaterial is in a form of dispersed micro-particles which are bulks formed by stacking two-dimensional nano-sheets. The TiS nanomaterial is a bulk formed by stacking two-dimensional nano-sheets, thereby having a laminated structure that improves the wave absorption effect. In addition, experimental results demonstrate that the TiS nanomaterial with a dose of 40 wt% has the most excellent wave absorption performance, with a minimum reflection loss up to -47.4 dB, an effective absorption bandwidth of 5.9 GHz and an absorption peak frequency of 6.8 GHz, which are superior to those of existing two-dimensional bulk materials. One of reasons for the excellent wave absorption performance of the TiS nanomaterial may be because the laminated micro-morphology of TiS results in the electromagnetic wave refraction loss.

Abstract: A detection probe and a fetal monitor. The detection probe comprises a probe body (2) and a mounting structure (1), detachably mounted on the probe body (2) and having a heart rate sensor for heart rate detection, a socket (4) for data transmission, and a lead line (5) for connecting the heart rate sensor and the socket (4) arranged thereon. A variety of functions can be achieved by means of a single detection device and thus the degree of integration is high; moreover, when the heart rate sensor is failed or aged, because the mounting structure (1) can be separated from the probe body (2), it is only necessary to repair and replace a corresponding part, so that the maintenance is convenient and the cost is reduced. Furthermore, the mounting structure (1) can also product the probe body (2) to some extent, and thus the anti-dropping capability of the detection probe is improved.
