Home blood glucose sensor works on which principle ?
Electrochemical
Electrochemical option is correct.
Home blood-glucose meters use disposable enzyme strips containing glucose oxidase (or glucose dehydrogenase). The enzyme reacts with glucose in the applied blood drop, and the electrons liberated by the redox reaction are transferred through a mediator to an electrode, producing a current that is proportional to the glucose concentration. This is a classic amperometric electrochemical biosensor.
Electrophysiological sensors detect bio-potentials such as ECG or EEG, purely chemical or physio-chemical sensors do not generate the electrical output on which glucose meters rely, so those principles do not describe the home glucose sensor.
