The existing breath detection methods are mostly contact or invasive methods, which are easy to bring discomfort to users. In real life, using wireless and non-invasive equipment to monitor the respiratory process in real time has become more and more important, which can not only reduce the pain of patients, but also provide sufficient information for the early detection and diagnosis of diseases. The parallel plate is coupled with the human body to form a coupling capacitance. The small displacement of the electrode in the process of breathing movement will lead to the change of capacitance value. The change of capacitance value is directly related to the distance between the electrode and the skin. There is no direct contact between the sensor and the human body, so as to realize the non-contact detection of respiratory information. In the wearable respiratory detection device designed in this study, the capacitance signal coupled by the parallel plate and the abdomen is collected by the fdc2214 capacitance sensor chip and transmitted to the mobile phone app through the microcontroller through the wireless LAN, so as to realize the real-time detection of respiratory signal. Healthy volunteers were recruited to participate in the comparative monitoring experiment using the existing mode and capacitive coupling mode. The experimental results show that the proposed method can stably measure the breathing of the experimental object, correctly reflect the breathing frequency of the experimental object, and the measurement error is within 3%. The research shows that the output signal of capacitive coupling monitoring respiratory signal has good reliability and feasibility. The experimental self powered sensing device can be used for real-time, continuous and noninvasive monitoring of subtle muscle movement and human respiratory state.","PeriodicalId":305829,"journal":{"name":"2022 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125042255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The existed research paid more attention to the effect of the myocardium during communication. However, experiments show the change of blood volume also has a great impact on signal transmission. In this paper, the cardiac cycle is divided into seven phases with different blood volumes periodically, and the signal gain is monitored through a homemade dynamic measurement platform with two peristaltic pumps and several silicone tubes. Through in vitro experiment of the porcine heart, the changes of two channel gains caused by the cardiac cycle are analyzed. The results show that channel gains change periodically with the change of blood volume in the cardiac cycle, and the change trends of the two channels are different because the signal paths in the two channels are different. For the Right Ventricle - Right Atrium channel, gain varies from −62 to −47 dB and channel gain is inversely correlated with blood volume. For the Right Ventricle - Left Ventricle channel, when blood volume is less than 80 mL, channel gain is about −51 dB. And when blood volume is greater than 80 mL, channel gain fluctuates around −48 dB. This study shows the gain of the intracardiac communication channel is affected by the change of blood volume in the cardiac cycle.","PeriodicalId":305829,"journal":{"name":"2022 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"23 11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125784881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of the current studies in this area only focuses on the characteristic input of surface Electromyography (sEMG) signals, but the acquisition and processing of sEMG are complicated and vulnerable to electromagnetic interference. The impedance signal has the advantages of easy acquisition and processing, strong anti-interference, non-invasive detection, and are widely used in the treatment of neuromuscular diseases. In this paper, impedance technique is introduced into grip force prediction. A single-frequency, low-intensity alternating current (AC) signal is injected into the brachioradialis muscle, and the change in muscle impedance is detected through the electrical effect of the electromagnetic field on biological tissue. Then, the correlation between impedance parameters and grip force changes is discussed, and the Long Short-Term Memory (LSTM) grip force prediction model is established with resistance (R) and phase (P) as feature inputs. The results show that the $r^{2}_score$ of the grip force prediction model is greater than 0.94 and the mean square error (MSE) is lower than 0.7. This paper restores the actual grip force based on the LSTM prediction model and provides a new implementation idea for grip force prediction.","PeriodicalId":305829,"journal":{"name":"2022 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128215077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
