In this paper, an in vivo experimental platform for measuring low back muscle impedance was established in order to detect the different force states of muscle and study the corresponding relationship between muscle force state and muscle impedance. In the experiment, Biering-Sorensen (BS) test was used to make the low back muscle contract continuously, and different weights (5 kg, 2.5 kg, 0 kg) were used to distinguish the force state of muscle. The impedance analyzer was used to measure the muscle impedance parameters under different load in the subject's low back muscle for studying the electrical impedance characteristics of different low back muscle states. The results showed that the relative resistance $R^{prime}$ of EIM was a downward trend with time and the 5 kg load had the fastest decline; The relative reactance $X_{c}^{prime}$ of EIM was an upward trend with time, the 5 kg load also had the fastest rise. The slope $k$ of the fitting curve of $R^{prime}$ and $X_{c}^{prime}text{were}-5.8times 10^{-4}$ and $8.76 times 10^{-4}$ respectively. Therefore, EIM can effectively detect the state of low back muscles.","PeriodicalId":305829,"journal":{"name":"2022 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"36 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":"125888417","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 purpose of this paper is to develop a miniature implantable system that can simultaneously record the bioelectrical activity of the gastric system and pace the gut in freely-behaving rodents, e.g., mice and rats. The system transmits the digitized gastric data to a stationary unit through a far-field 2.4 GHz bidirectional communication link and receives back the stimulation configurations instructed by the user, in real-time. In addition, an under-the-cage charging unit establishes an inductive near-field 13.56 MHz wireless power and data transfer with the implantable system and in presence of the body movements and stomach motility of the subject, delivers a constant power to the implant through a closed-loop system. The benchtop validation of the system showed appropriate frequency response of the analog conditioning circuit in the range of 16 mHz to 1.6 Hz and the capability of the implant to generate monophasic and biphasic electrical pulses at amplitudes and frequencies up to ±10 mA and 10 kHz, respectively. In addition, it was demonstrated that the charging unit can generate an adjustable output power between 100 mW and 1000 mW and provide a constant rectified voltage of 3.8 V at the implant.","PeriodicalId":305829,"journal":{"name":"2022 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"43 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":"129635437","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}

To examine the performance of the system, conductivity resolution experiments; simulated heartbeat frequency detection experiments and the axial distance change to measured target experiments were performed. Results show that the system introduced in this paper can effectively detect the cardiogenic pulsation of CBF volume, which is expected to break the time window effect caused by imaging examinations and provide a new bedside real-time technology for CBF perfusion monitoring.","PeriodicalId":305829,"journal":{"name":"2022 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"43 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":"127882262","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 body-antenna coupling effects are investigated by using a three-layer tissue model. The body-antenna coupling strength is inversely proportional to the body-antenna separation distance and the optimum body-antenna separation distance of one-eighth free space wavelength can be applied to wearable applications.
