A gastrointestinal motility detection capsule utilizes bidirectional ultrasound probe pairs to simultaneously obtain the distances from the capsule to the opposite sides of the gastrointestinal tract section. By adding the distances with the distance between the probe pair, a directional cavity diameter is obtained, which can eliminate data fusion errors caused by capsule movement. Based on multiple directional cavity diameters, gastrointestinal morphological features such as curvature, average diameter, volume, anatomical position, and 3D dynamics are acquired. Based on the time series of the features, gastrointestinal motility parameters such as peristaltic frequency and intensity, capsule movement trajectory, and emptying time are obtained. The capsule is to be used in routine gastrointestinal motility checks and disease diagnosis. The examinee does not need to clean the gastrointestinal tract and can pair it with different diets, making it convenient for self-examination at home or hospital check-ups.

A method for performing guided self-examination of a subject's tissues is described. The method includes: positioning a handheld device comprising multiple electrodes and a certain amount of flexible material in general contact with a region of the subject's body; measuring the capacitance between two of the electrodes; calculating tissue parameters based on the capacitance; determining instructions for the subject in a controller based on the tissue parameters; and issuing instructions to the subject to guide the subject in manipulating the handheld device.
