Abstract
This paper presents a system for measuring the bioimpedance of a wound, to give an indication of its healing progress without the need to remove the wound dressing. A 16-channel electrode array is printed on a composite nanocellulose-polyurethane substrate that is stretchable, breathable and biocompatible. An electronic readout system consists of an analogue multiplexor, analogue front end interrogated with an integrated impedance measurement device, and an on-board calibration circuit. The readout electronics is implemented on a polyimide flexible substrate, including additional sensing functions, wireless powering and radio communications easily integrated in various wound dressing scenarios. The electrode array is detachable from the readout allowing numerous application specific electrode patch configurations, and reuse of electronics with disposable, single-use electrode patches. The system is characterized measuring a range of known impedances, for measurements on a gelatine phantom and on a healthy human arm.
