Abstract: An electrochemical sensor includes a base member, a conductor disposed on the base member, an insulating layer covering the conductor with a portion of the conductor exposed, a silver/silver chloride electrode formed on at least the exposed portion of the conductor, and a water-permeable organic layer covering the silver/silver chloride electrode.

Abstract: A measuring apparatus for measuring a substrate concentration by using a sensor including an enzyme reagent layer includes a state detecting unit that applies a first voltage and a second voltage different from the first voltage to the sensor to detect a state of the enzyme reagent layer based on a difference between a first response current value obtained under application of the first voltage and a second response current value obtained under application of the second voltage.

Abstract: The present invention provides a sensor insertion and removing device which is user-friendly and which does not cause infection. The sensor insertion and removing device has a sensor; a puncture blade member; a housing which houses the sensor and the puncture blade member; a guide part which is provided within the housing and which glidably supports the puncture blade member; a puncture blade operating part which inserts the sensor under the skin by causing the puncture blade member to glide along the guide part integrally with the sensor, upon delivering the puncture blade member outside the housing to puncture the skin, and which causes the puncture blade member to glide along the guide part in a state of being separated from the sensor, upon removing the puncture blade member from under the skin into the housing, and a sensor operating part which pulls out the sensor from under the skin and removes it from under the skin into the housing.

Abstract: The present invention provides an electrochemical sensor comprising a substrate, an electrically conductive layer made of carbon particles which is disposed on the substrate, a cell membrane mimetic structure layer containing an enzyme at least one of inside the cell membrane mimetic structure layer and on the interface of the cell membrane mimetic structure layer which is disposed on the electrically conductive layer.

Abstract: When continuous user biometric information is transmitted to a server device continuously from a handheld device used by a user, the server device can be caused to receive a required measurement value efficiently at a required time, select information desired by the user on the basis of the measurement value and user peripheral information, and provide the user with the information reliably, without imposing excessive communication charges and the like. A server device 140 is used together with a handheld device 110 that transmits the user peripheral information to the server device and receives the information transmitted from the server device.

Abstract: A biosensor includes a first working electrode that a biocatalyst, which has a property that reacts on a specified ground substance, is disposed, a second working electrode that the biocatalyst, which the property is lost, is disposed, and at least one counter electrode for respectively applying a voltage to the first working electrode and the second working electrode.

Abstract: Provided is an analysis device or an analysis method, by which highly reliable analysis results can be obtained even in the circumstances where environment temperature changes, while reducing load on the user. The analysis device (1) is provided with a determining means (13) which determines whether environmental temperature measured by means of a temperature measuring means (6) is within a predetermined temperature range or not. The determining means (13) is so configured as to determine whether the environmental temperature is within the predetermined temperature range or not, even in the circumstances where information relating to a target substance in a sample cannot be obtained from the analysis device.
