Abstract
The disclosure relates to a microfabricated sensor (1) comprising at least one hollow microneedle (2) for minimal invasive extraction of a sample of bodily fluid, a fluid channel (3) connected to the at least one microneedle for receiving a sample of bodily fluid extracted by the at least one microneedle, a microwave transmission line (4) coupled to and extending along at least a portion of the fluid channel, such that the dielectric properties of the fluid in the fluid channel provide an influence on the electrical properties of the transmission line. The disclosure further relates to a method of microfabricating such a sensor and a method of sensing the level of a component in bodily fluid of a patient by providing such a sensor.
