Small fiber peripheral neuropathy is an early complication of diabetes. Electric skin response to some stimulus, as electrochemical skin conductance ECS, is a promising route in the early follow‐up of such diseases. It is related to sweat gland innervations and their permeability to chlorides and protons; it is non‐invasive, quantitative and reprod...

AISI 304L is used in SudoscanTM technology (Impeto Medical Inc.) for the early diagnosis of small fiber neuropathy caused by type-2 diabetes or cystic fibrosis. In a recent paper, several substitute electrodes were analyzed, among which the biocompatible nickel-free AISI 430 appeared as an interesting material. In the present work, we compare in de...

Les neuropathies périphériques sont des dysfonctions causées par certaines maladies (diabète, mucoviscidose). Celles-ci peuvent être rapidement diagnostiquées par la technologie SudoscanTM. Cette technologie non invasive, est basée sur des mesures électrochimiques via l’imposition de faibles potentiels entre des électrodes appliquées sur la peau et...

A non-invasive device based on measurements of electrochemical skin conductance can detect small fiber neuropathy, a sweat gland dysfunction implicated in several diseases. The measurement is related to sweat composition and notably to chloride concentration. To optimize the electrode material, in vitro experiments are performed in mimetic sweat so...

Small fiber neuropathy is a dysfunction caused by diseases such as type II diabetes and cystic fibrosis. Nowadays, it is possible to analyze neuropathy with Sudoscan TM technology (Impeto Medical Inc.) which provides a rapid and non-invasive early diagnosis. This technology is based on measurements of the electrochemical conductance of the skin via...

Stainless steel is gaining increasing interest as an anodic material in bioelectrochemical systems and beginning to challenge the more conventional carbon-based materials. Here, microbial bioanodes designed under optimal conditions on carbon cloths gave high current densities, 33.5 + 4.5 A m -2 at -0.2 V/SCE, which were largely outstripped by the c...

The abilities of carbon cloth, graphite plate and stainless steel to form microbial anodes were compared under identical conditions. Each electrode was polarised at −0.2 V vs. SCE in soil leachate and fed by successive additions of 20 mM acetate. Under these conditions, the maximum current densities provided were on average 33.7 A m−2 for carbon cl...
