High performance glucose sensor

Abstract

A highly accurate glucose sensor that detects glucose by transmitting and receiving sensing signals in a radio or microwave frequency range of the electromagnetic spectrum is provided. The glucose sensor has at least two antennas at least one of which operates as a transmit antenna to transmit one or more of the sensing signals and at least one of which operates as a receive antenna, and the glucose sensor has a mean absolute relative difference (MARD) value of about 5.0% to about 9.9%, or of about 5.0% to about 7.0%, or of about 5.0%.
