MICRO-THERMOCOUPLE
First Claim
1. A micro-thermocouple comprising an elongated first microwire electrode and an elongated second microwire electrode with an electrical insulating barrier between the first and second electrodes throughout a portion of the length thereof, one of said electrodes formed of an amorphous metallic material, and an electrically conductive thermocouple junction, including a length of one of the electrodes wrapped about the other electrode.

Abstract
Improved, high-strength micro-thermocouples (10) are provided, which include first and second microwires (12, 14) each preferably in the form of an elongated metallic core (18, 22), with an outer glass coating (20, 24); at least one of the microwires (12, 14) is an amorphous microwire (12), and in preferred forms the other microwire is a crystalline microwire (14). The thermocouple junction (16) is formed by stripping the distal ends of the microwires (12, 14) to provide stripped ends (18a, 22a). The stripped crystalline microwire end (22a) is wrapped about the stripped amorphous microwire end (18a) to form a series of abutting convolutions (30). The micro-thermocouples (10) find particular utility in the fabrication and repair of carbon fiber composite materials, such as airplane components.
