EIT Imaging of Lung Ventilation

Electrical impedance tomography (EIT) provides functional images of an electrical conductivity distribution inside the human body. It has been used for the continuous monitoring of physiological functions such as lung ventilation and perfusion. The image contrast represents the time change of the electrical conductivity distribution inside the human body. Since the 1980s, many potential clinical…

Conductive Fabric Sensor

There has been considerable attention drown to conductive fabric pressure sensors in the field of wearable sensors . This type of sensors has several advantages including flexibility, low-cost, and washability. These devices have a wide range of applications, including in smart textiles, tactile sensors, artificial skins, and patient’s movement monitoring technologies. Recently, we used electrical…

Conductive Membrane Pressure Sensor using EIT

There is a growing demand for cost-effective flexible pressure sensors. These devices have  wide   potential applicability, including in smart textiles, touch screens, artificial skins , and wearable health monitoring technologies. Electrical measurements have recently been used to measure the pressure-induced surface deformation of  conductive membranes. In particular, electrical impedance tomography (EIT) has been used…
