Bioimpedance Spectroscopy
In the context of biology, electrical phenomena are usually identified with ionic currents through protein channels, for example as they are postulated during nerve signalling (Andersen et al. Prog Neurobiol 88(2):104–113, 2009; Sakmann and Neher Annu Rev Physiol 46:455–472, 1984). However, there are more electrical phenomena that play a significant role in biological systems, namely those aris...
متن کاملBioimpedance Devices for Detection and Management of Lymphedema
Bioimpedance, which uses resistance to electrical current in comparing the composition of fluid compartments, could potentially be used as a tool to diagnose lymphedema. There is minimal information about the technical and diagnostic performance of bioimpedance testing in the diagnosis (surveillance) of secondary lymphedema; especially for subclinical disease. In addition, there are no data fro...

متن کاملEarly diagnosis of lymphedema using multiple frequency bioimpedance.
Multiple frequency bioelectrical impedance analysis (MFBIA) has previously been shown to provide accurate relative measures of lymphedema in the upper limb of patients (1). This paper reports the results of a three year prospective study to evaluate the efficacy of MFBIA to predict the early onset of lymphedema in patients following treatment for breast cancer. Bioelectrical impedance measureme...
متن کاملBioimpedance spectroscopy tensor probe for anisotropic measurements
The tetrapolar electrode configuration used in bioimpedance suffers from negative sensitivity and is confounded by anisotropic tissue such as blood vessels or muscle and nerve fibres. We propose a circular array of electrodes to focus current directly underneath the probe and provide anisotropy information. We show that an implementation using 16 miniature electrodes is able to outperform the t...
