Abstract
A pulse oximeter includes a curved holder. A flexible substrate is coupled to a curved inner surface of an outer portion of the curved holder. A light emitter, a light receiver, and a reinforcement are coupled to a curved inner surface of the flexible substrate. The reinforcement is curved to extend in conformance with the curved form of the flexible substrate. The material of the reinforcement has a Young's modulus that is larger than the Young's modulus of the material of the outer portion and the Young's modulus of the material of an inner portion.
