Variable frequency bioimpedance instrumentation
The 26th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005The design of instrumentation used to measure the bioimpedance of skin or tissue is presented. An inexpensive, component level approach, appropriate for use by researchers rather that commercial applications, is emphasized. The design and implementation process is thoroughly explained and design tradeoffs are discussed with relation to various ...

Bioimpedance Spectroscopy of the Breast
Lymphatic Research and Biology, 2020Background: Bioimpedance spectroscopy (BIS) measurements of breast lymphedema poses practical and technical challenges, in particular the determination of the resistance at zero frequency (R0), the index of change in breast lymph content. Conventionally, R0 is calculated from data analysis by using a procedure eponymously known as Cole modeling, a ...

Human in vivo liver and tumor bioimpedance measured with biopsy needle
Physiological Measurement, 2022Objective. Liver biopsy is an essential procedure in cancer diagnostics but targeting the biopsy to the actual tumor tissue is challenging. Aim of this study was to evaluate the clinical feasibility of a novel bioimpedance biopsy needle system in liver ...

Bioimpedance and Bioimpedance Vector Analysis in patients with Anorexia Nervosa
European Eating Disorders Review, 2012AbstractObjectiveThe utility of bioelectrical impedance analysis (BIA) in patients with anorexia nervosa (AN) is imperfectly defined. Furthermore, any advantage accrued by BIA with vector analysis (BIVA) is unknown.MethodWe conducted a retrospective analysis of 57 women with AN admitted to our service who underwent BIA and BIVA. Twenty‐seven women were

Thoracic bioimpedance estimates cardiac output based on the principle that each heartbeat induces a decrease in the electrical impedance of an electrical current applied through the thorax and that this decrease is proportional to stroke volume. It is a completely noninvasive and easy-to-use technique.

A Wideband Electrical Impedance Tomography System Based on Sensitive Bioimpedance Spectrum Bandwidth
IEEE Transactions on Instrumentation and Measurement, 2020A wideband electrical impedance tomography (EIT) system based on bioimpedance spectrum (BIS) analysis was proposed to image biological objects. The system integrated 16 electrodes to realize driving and measurement over 1 kHz–1.1 MHz.

Single-Channel Bioimpedance Measurement for Wearable Continuous Blood Pressure Monitoring
IEEE Transactions on Instrumentation and Measurement, 2021Pulse transit time (PTT) sensing technology is rapidly evolving for cuffless continuous blood pressure (BP) monitoring. However, PTT-based BP methods must implement multidevices that could impede wearable applications.
