In this paper the determination of the positions of surface plate electrodes on human trunk for measuring the breathing and heart rate by using the electrical bioimpedance is presented. The designed and implemented measurement device — electrode shirt — is described. The novelty of current work is incorporated into the solution of placing the large surface plate electrodes into the garment. Focus...
This paper presents an impedance plethysmography system suitable to perform a continuous monitoring of human breath activity. The problem of motion artifact is mitigated through the use of a correction technique exploiting an additional inertial sensor able to detect movements of the arms of the subject under test. The correction algorithm is based on a simple correlation technique and only requires...
This paper shows an instrument that uses electronic technology to characterize the effects of the diabetes in tissues, by measuring changes in the skin impedance on the sole. The bioimpedance system generates a signal at different frequencies and supplies it to the tissue via electrodes. This system uses the 3 electrodes technique: the first electrode where the generator signal wave at different frequencies...
Physicians' understanding of biosignals as measured with medical instruments becomes the foundation of their decisions and diagnoses of patients, as they rely strongly on what the instruments show. Thus, it is critical and very important to ensure that the instruments' recordings exactly reflect what is happening in the patient's body so that the acquired signal is the real one or at least as close...
This paper reports a MEMS-based impedance spectrometer capable of detecting a single MDA-MB-231 human breast cancer cell in a background of normal MCF10A breast epithelial cells. This has been achieved by 1) stimulating a selective increase in the cancer cell area using the FDA-approved anti-cancer drug SAHA which resulted in a cancer-specific rise in bioimpedance and 2) utilizing a unique thin multi-branched...
A conventional method for measuring abdominal pressure involves the use of a fluid-filled rectal catheter. However, this method has some drawbacks, so it is limited to ambulatory urodynamics monitoring study. In this study, we proposed a novel method for estimating abdominal pressure in non invasive manner by changes in bio-impedance and electromyographic (EMG) signals. As a preliminary, we compared...
