Disclosed is a glucose measuring apparatus including a pressure measurer having an elastic part or a pressure sensor, that measures a pressure applied to an object, a film that comprises a first optical waveguide configured to be close to the object, a near infrared ray (NIR) irradiator that irradiates an NIR to the first optical waveguide if the measured pressure is greater than or equal to a preset value, an NIR receiver that receives an attenuated total reflection NIR (ATR-NIR) from the first optical waveguide, and an analyzer that measures a blood glucose level based on the ATR-NIR, wherein the film is an independent module that can be combined with and separated from the glucose measuring apparatus.

Certain aspects of the disclosure are directed to an apparatus including a scale and external circuitry. The scale includes a platform, and data-procurement circuitry for collecting signals indicative of the user's identity and cardio-physiological measurements. The scale includes processing circuitry to process data obtained by the data-procurement circuitry, therefrom generate cardio-related physiologic data, and to send user data to the external circuitry. The external circuitry identifies a risk that the user has a condition based on the reference information and the user data provided by the scale and outputs generic information correlating to the condition to the scale that is tailored based on the identified risk.

A method for determining the dry weight of a patient after dialysis therapy, wherein the patient's blood volume is monitored and blood volume values are output. The blood volume values are recorded and evaluated for a predetermined period of time after reaching an ultrafiltration volume appropriately predetermined for the patient, wherein the dry weight of the patient then is determined on the basis of the rate of change of the blood volume during the predetermined period of time.

An electrochemical electrode for use in a biosensor. The electrode comprises a substrate, a palladium metal layer manufactured on the substrate, and a palladium oxide-containing layer manufactured on the palladium metal layer. The palladium metal layer has a thickness of no more than 90 nm, and the palladium oxide-containing layer has a thickness of no more than 40 nm.

Disclosed herein are apparatuses for manipulation of an ear device within the ear canal of a subject.
