Outline of Final Research Achievements

In this study, our final objective is developing a wearable electrical impedance tomography (EIT) that can achieve electrode contactless EIT measurement for monitoring of lung disease in variety of chest shape.
A wearable EIT system was developed included flexible printed circuit board and small size of battery driven circuit board with a Bluetooth module. The system could run for 1 hour continuously and its total weight was 100g.
In addition, we developed a novel algorithm for chest shape estimation and a single channel electrode contactless impedance measurement circuit. The software could estimate chest shape on real-time and the circuit could measure change in tidal volume with good correlation with that measured by flow sensor. Both technology will be added into the EIT system in near future.
