A disposable self-sensing signal test strip includes a test strip body. The test strip body has a detection area and a circuit area. The detection area has a detection circuit. An electrochemical processing unit, a wireless transmission unit, and a power source unit are provided in the circuit area. The detection circuit is electrically connected to the electrochemical processing unit. The electrochemical processing unit sends to the detection circuit a control signal for performing detection. After receiving the control signal, the detection circuit reacts electrochemically with the test sample and sends a feedback signal to the electrochemical processing unit. The electrochemical processing unit converts the feedback signal into a detection parameter signal and sends the detection parameter signal through the wireless transmission unit to a receiving unit. The power source unit supplies electricity to the electrochemical processing unit and the wireless transmission unit.

An electrocardiography monitor is provided. A sealed housing includes one end wider than an opposite end of the sealed housing. Electronic circuitry is provided within the sealed housing. The electronic circuitry includes an electrographic front end circuit to sense electrocardiographic signals and a micro-controller interfaced to the electrocardiographic front end circuit to sample the electrocardiographic signals. A buzzer within the housing outputs feedback to a wearer of the sealed housing.

A monitor and indicator system includes a sensor part, a control and indication part, and a power part. The monitor and indicator system is configured to: (a) monitor a concentration of a sterilant in a sanitizing solution; (b) determine a depletion of the sterilant upon detecting that the concentration of the sterilant becomes equal to or falls below a predetermined threshold concentration level; and (c) indicate the depletion of the sterilant of the sanitizing solution by emitting a notification.

Provided is a method for measuring a component of a biological sample with a biosensor provided with: a capillary for introducing the biological sample; an electrode part including a first electrode system that includes a first working electrode and a first counter electrode in the capillary; and a reagent part disposed so as to be in contact with the electrode part, the reagent part containing an enzyme and a mediator, and the method including a step of starting voltage application for a duration longer than 0 second and up to 0.7 second to the first electrode system within 0 second to 0.5 second after detection of the introduction of the biological sample to obtain a hematocrit value based on a current value obtained thereby.

A source of formaldehyde for methylating a primary or secondary amine is part of an electrochemical measurement. The source of formaldehyde may be an adduct of formaldehyde.

Long-term electrocardiographic and physiological monitoring over a period lasting up to several years in duration can be provided through a continuously-recording insertable cardiac monitor. The sensing circuitry and the physical layout of the electrodes are specifically optimized to capture electrical signals from the propagation of low amplitude, relatively low frequency content cardiac action potentials, particularly the P-waves that are generated during atrial activation and storing samples of captured signals. In general, the ICM is intended to be implanted centrally and positioned axially and either over the sternum or slightly to either the left or right of the sternal midline in the parasternal region of the chest.

The present disclosure relates to an electrochemical sensor including: a substrate: a plurality of working electrodes formed on the substrate; and a single reference electrode formed on the substrate, wherein a separation distance between the single reference electrode and the plurality of working electrodes formed around the reference electrode satisfies Equation 1 below, and a method for manufacturing the same.

A coated electrode includes an electrode, a coating configured to immobilize biomolecules, and a coating configured to improve electron transfer rate. Methods of making the coated electrode are also provided. A biosensor comprises a plurality of electrodes, each electrode including the coated electrode.

Fire present invention relates to new electrochemical probes for the measure of an analyte selected from the group consisting of: free chlorine, chlorine dioxide, total chlorine and peracetic acid; characterized in that said probe includes at least a printed electrode nano- or micro-structured whit a nano- or micromaterial selected from the group consisting of: nano- or microparticies of carbon black and/or nano- or microparticles of a metal selected from the group consisting of gold, silver, platinum, copper and combinations or alloys thereof.

A method is provided for determining analyte concentrations, for example glucose concentrations, that utilizes a dynamic determination of the appropriate time for making a glucose measurement, for example when a current versus time curve substantially conforms to a Cottrell decay, or when the current is established in a plateau region. Dynamic determination of the time to take the measurement allows each strip to operate in the shortest appropriate time frame, thereby avoiding using an average measurement time that may be longer than necessary for some strips and too short for others.
