▎ 摘　　要

NOVELTY - The ring has a belt-shaped structure formed by connecting a P-type thermoelectric support leg and an N-type thermoelectric support leg with a fiber base-band as a base. Connection points are alternately located at two sides of the fiber base-band. USE - Flexible fiber-based thermoelectric hand ring. ADVANTAGE - The ring utilizes the fiber base cloth to construct the thermoelectric hand ring structure, and realizes heat gradient utilization vertical to skin direction of a human body. The ring is simple and easy to use, light in weight and flexible and easy to wear, and has low manufacturing cost and better prospect in the intelligent textile field, and provides a direction for cleaning a wearable product. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the flexible fiber-based thermoelectric hand ring. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a flexible fiber-based thermoelectric hand ring.
