  • Patent number: 11125737
    Abstract: A microcapillary sensor array includes a sensor body that is elongated along a longitudinal axis. The sensor body has a first end, a second end spaced from the first end along the longitudinal axis, an outer surface, and an inner surface. The inner surface defines a hollow capillary that extends from the first end toward the second end along the longitudinal axis. The microcapillary sensor array includes a sensing element that extends through the sensor body from the outer surface to the hollow capillary and a conductive element in contact with the sensing element. The conductive element detects a response signal generated by a reaction between the sensing element and a fluid as the fluid flows through the hollow capillary contacting the sensing element.
