1. A foldable electronic device, comprising:
a main body part, having a first main body including a first display and a second main body including a second display, configured to fold along a folding line such that the first display and the second display face each other when the main body part is folded along the folding line;
a first sensor provided on the first main body, and configured to obtain a contact image of an object of a user placed into contact with the first main body;
a second sensor provided on the first main body, and configured to measure a degree of folding of the first main body relative to the second main body while the object is placed into contact with the first main body; and
a processor configured to estimate bio-information of the user, based on a signal obtained from the contact image of the object and the degree of folding,
wherein the obtained signal provides bio-information corresponding to one or more of blood pressure, vascular age, arterial stiffness, aortic pressure waveform, vascular compliance, stress index, and fatigue level of the user.
