With the continuous development of science and technology,new nano-functional devices such as nano-sensors,micro-generators,and biomass-based electrical functional components have gradually been developed,and their development enthusiasm has endured for a long time.Among them,biomass materials have gradually been developed and applied to the development of microelectronic devices due to their good biocompatibility,electrical drive,electrical sensing and mechanical properties.For this reason,this article aims at the problems of poor biocompatibility,high cost,and poor sensing performance of traditional ion gel sensors,and uses starch as the basic polymer to manufacture biological gel sensors,and proposes the preparation process of biological gel sensors.In order to solve the problem of poor sensing performance of the biogel sensor,a biological gel sensor induced by the principle of electric eel nerve conduction was prepared through a method of biomimetic construction of the principle of electric eel nerve conduction.The biological gel sensor was induced according to the electric eel nerve conduction principle(bionic biological gel sensor).Then we study the sensing performance of the bionic biological gel sensor and the law of electrical signal changes under different external stimuli by using a self-made sensing test device.Also we clarify that the bionic biological gel sensor responds to electrical changes when the external stimulus changes.And the principle of signal change is given the application of biomimetic biological gel sensor in human body sign sensing.The main research includes the following aspects:Firstly,using green and cheap starch as the main polymer,high-conductivity polymer and biogel sensor doped with moving ions are prepared.And put forward the preparation method of the biogel sensor.Using controlled variables and electrochemical analysis methods,the performance improvement methods of biogel sensors are studied,and the performance improvement effects are verified through sensor test experiments.Secondly,based on the research on the principle of electric eel nerve conduction and the principle of electric eel biological discharge,the principle and method of bionic transformation of biological gel sensor with ion exchange membrane are studied,and an electric eel nerve conduction principle induction biological gel sensor with a sandwich structure is proposed.We used sensor tests to confirm that the bionic structure can successfully increase its sensitivity.Through the controlled variable method and electrochemical analysis method,the types of ion exchange membranes on both sides of the biogel sensor in the biological gel sensor induced by the principle of electric eel nerve conduction are studied.The type of ion-exchange membrane,an electric eel nerve conduction principle induced biological gel sensor with excellent sensing performance and high sensitivity is proposed.And then the electric eel nerve conduction principle induced biological gel sensor with excellent sensing performance and high sensitivity is proposed.Thirdly,aiming at the application research of the biological gel sensor induced by the electric eel nerve conduction principle,the influence of different stresses on the biological gel sensor induced by the eel nerve conduction principle is explored,and the direction of its most force is given.Then we study the stress change on the bionic induced biological gel sensor,and give the stress-response electric signal change law curve by the controlled variable method.At the same time,the influence of stress frequency change on the sensor signal of the sensor.The different kinds of response electrical signals are affected by changes in stress frequency.In addition,by changing the temperature and salinity of the biomimetic biological gel sensor,the influence of the sensor signal on the external temperature and salinity changes is studied,and the control variable is adopted.In the method experiment,the law curve of the response voltage signal of the biomimetic gel sensor with the change of the two is given respectively,and the principle of temperature and salinity on the change of the sensor signal is explained.The last one,based on the research on the sensor performance of the biological gel sensor induced by the principle of electric eel nerve conduction and the law of electrical signal changes caused by changes in external stimulus factors,the application of the sensor in human body sign sensing and health monitoring is studied,and experiments are adopted.Exploring the method,it is found that it performs well in the process of heartbeat,pulse,body temperature and human movement monitoring,confirming the possibility of its application in human body sign sensing and health monitoring.
