The invention belongs to the technical field of hydrogel materials, and particularly relates to degradable self-healing chitosan composite aldehyde guar gum hydrogel as well as a preparation method and application thereof. The method comprises the following steps: 1) obtaining a chitosan (CHI) solution; 2) preparing a solution of aldehyde guar gum (AGG); and 3) carrying out a reaction on the solution of aldehyde guar gum with the solution of chitosan to prepare the degradable self-healing chitosan composite aldehyde guar gum hydrogel. According to the preparation method, an aldehyde group on an AGG chain and an amino group on a CHI chain are subjected to a Schiff base reaction to form an imine bond, and the CHI/AGG hydrogel is obtained by taking the imine bond as a cross-linking point. Dueto a dynamic crosslinking mechanism, the hydrogel can realize self-healing within 5 minutes and can be degraded near a neutral environment.

The invention relates to a fuse sensor circuit, which comprises an amplifying unit, a fuse, a reference resistance, a switch unit, a latch unit and a shunt resistor. The shunt resistor can be connected in parallel with the fuse when the sensor controlling signal controls the opening of the fuse sensor circuit, so that the shunt resistor can bear more current distribution to ensure that the current flowing through the fuse is not too large. Therefore, the amplification unit parallelly superimposes the current in the fuse and the current in the shunt resistor to obtain a large current input to improve the sensitivity of the sensor circuit. The fuse sensor circuit can reduce the strength requirement for the programming voltage or programming current for fuse programming, and is suitable for relatively low programming voltage or programming current.
