Development of a Wearable Miniature Flexible Finger Capillary Microscope

Abstract

Human capillaries are closely related to physical condition. In order to accurately assess changes in physical condition, we have developed a small, flexible capillary microscope that can be worn on the fingertip. Vertical adjustment made it possible to focus the microscope. An angle-adjustable illumination device was fabricated, and the surface in contact with the finger was made flexible. By analyzing the captured images, changes in physical condition can be estimated. Image processing will be used to analyze capillary shapes and individual differences to find associations. In the future, we aim to propose a more rational physical condition management method that can easily grasp a person's health condition.
