An electronic device is provided. The electronic device according to an embodiment includes a Photoplethysmography (PPG) sensor including a light source, a detector and a transparent electrode window and a processor configured to, based on determining that a user is in contact with the PPG sensor based on a value sensed by the transparent electrode window, activate the detector, and determine whether a contact between the PPG sensor and the user is poor based on an illuminance value sensed by the detector.

PPG sensor, electronic device comprising same, and control method thereof

A polymeric film composition and a non-enzymatic glucose sensor including the functional polymeric film are provided. The polymeric film composition includes polyurethane and perfluorosulfonic acid polymer.

Polymeric film composition for non-enzymatic glucose sensor and non-enzymatic glucose sensor including the same

A new ferrous complex capable of being used as an electron transfer mediator for a glucose sensor, a biosensor, and the like, is provided, which measure a glucose concentration in blood, in which the new ferrous complex exchanges rapidly and smoothly an electron between an enzyme and electrode, is strongly absorbed into electrode, and is stable, so that the new ferrous complex allows excellent sensitivity of a glucose sensor to be maintained.
