Claim:
1. A sensing apparatus configured to use a radio frequency signal to perform sensing, the apparatus comprising: a protecting layer configured to protect a substrate from a migration of electrons occurring as the radio frequency signal is applied to a first electrode and a second electrode; a channel forming layer comprising a polarized carbon-based nano material, disposed between the first electrode and the second electrode, the channel forming layer being configured to form a channel based on a field between the first electrode and the second electrode; and a sensing layer disposed on the channel forming layer, comprising a medium material, the sensing layer being configured to sense, in a predetermined period of time, a concentration of glucose permanently bonded by an oxidant to a medium material, a hexagonal-boron nitride (h-BN) layer disposed between the channel forming layer and the protecting layer, wherein a side surface of the h-Bn layer directly contacts a side surface of the first electrode, another side surface of the h-Bn layer directly contacts a side surface of the second electrode, and a top surface of the h-BN layer directly contacts the channel forming layer, wherein the respective bottom surfaces of the first electrode, the second electrode, and the h-BN layer are disposed on top of, and directly contact, a surface of the protecting layer, wherein the concentration of glucose is measured based on an S parameter value and an RLGC value obtained as a result of a high frequency electrical signal being applied to the first electrode and the second electrode.
