Auto-Tuned Induction Coil Conductivity Sensor for In-Vivo Human Tissue Measurements

Abstract: Auto-tuned induction coil technology, based upon phase-locked loop circuitry (PLL), was developed and shown to be an effective tool for in-vivo measurement of electrical conductivity of human tissues. Because electrical contact is not required, several disadvantages of the electrode method for conductivity determination are avoided, such as electrode polarization and variable conductivity associated with the stratum corneum of the epidermis. Fixed frequency excitation is supplied to a parallel tuned RLC circui… Show more

“…In those cases where conductivity showed age dependency (5 sites), conductivity always declined with increased age. As discussed briefly in our companion paper [1], increased extremity elevation was shown to lead to increased electrical conductivity. Here we explored that effect with just the right mid-volar forearm.…”

“…As indicated in our previous work [1], the ICCS instrument targets soft tissues residing in a region extending from the skin surface to a depth of about 15 mm beneath the epidermal surface. In either clinical, we identified seven locations on each side of the body as measurement sites, for a total of fourteen.…”
