Electrical Active Sensing of Body Structure and Functions

Abstract

Fast and accurate visualization of body dynamics such as body composition, musculoskeletal state, body motion and interaction with environment is expected to evaluate and optimize the body function, thus giving contribution to the extension of healthy life expectancy and the enhancement of QoL. For developing a miniaturized measurement device that is in harmony with human body, combination of smart detection by electrical sensing and estimation by machine learning seems to be effective. The author has been studying about the active electrical sensing by using electrical excitation of the target to scan the internal and surface impedance distribution. The examples are body composition monitoring and muscle injury detection, hand motion capture from forearm deformation, and visualization of pressure distribution. In this presentation, the author introduces a part of these studies.
