Glucose sensor

The invention relates to a glucose sensor. An example apparatus includes an electrochemical cell configured to generate a first electrical signal indicative of an amount of glucose in a bodily fluid of a person, the electrochemical cell including a working electrode, a counter electrode, and a reference electrode; and a background electrode configured to not catalyze a reaction with glucose and configured to generate a second electrical signal indicative of an amount of electrochemical interference proximate to the electrochemical cell. 本公开涉及葡萄糖传感器。一种示例性装置，包括电化学电池，该电化学电池被配置为生成指示人的体液中的葡萄糖的量的第一电信号，该电化学电池包括工作电极、对电极和参考电极；以及背景电极，该背景电极被配置为不催化与葡萄糖的反应并且被配置为生成指示靠近该电化学电池的电化学干扰的量的第二电信号。
