Abstract
Embodiments relate to a monolithic arrangement comprising one or more electrochemically responsive electrodes that are configured to generate a signal relating to a characteristic of a fluid sample; and one or more electronic circuits for processing signals generated by the at least one electrode. Optionally, the monolithic arrangement comprises a plurality of electrodes configured to implement potentiostat and/or galvanostat measurement techniques. Optionally, at least two of the plurality of electrodes have different electrochemical material layers to obtain correspondingly different electrode functionalization.
Core Innovation
The invention provides a multi-channel electrochemical system using a multi-channel integrated-circuit or IC-based electrochemical (MTIC) transducer. A plurality of electrochemically responsive electrodes in the MTIC transducer generate signals relating to a characteristic of a fluid sample, and at least one electronic circuit processes signals generated by the plurality of electrodes while on-chip memory stores data relating to the signals.
The electrodes, the at least one electronic circuit, and the on-chip memory are incorporated in the same monolithic arrangement. The electronic circuit processes data relating to signals provided by the plurality of electrochemically responsive electrodes and derives an expiry date of the MTIC transducer based on the processing of the data.
The invention further covers a method for measuring parameter values pertaining to one or more fluid samples in which a monolithic arrangement is operably engaged, the monolithic arrangement including at least one MTIC transducer. The at least one MTIC transducer includes one or more electrochemically responsive electrodes configured to contact organ tissue of a user, and signals are processed that are generated in response to making contact with bodily fluid discharged by the organ tissue, with an analysis module determining an expiry date of the MTIC transducer.
Claims Coverage
The document includes three independent claims. They collectively cover monolithic MTIC integration, on-chip memory, and expiry-date determination based on processed signal data.
Monolithic multi-channel MTIC transducer with integrated electrodes, signal processing, and expiry-date derivation
A multi-channel integrated-circuit or IC-based electrochemical (MTIC) transducer comprising a plurality of electrochemically responsive electrodes operable to generate signals relating to a characteristic of a fluid sample; at least one electronic circuit for processing signals generated by the plurality of electrodes; and on-chip memory for storing data relating to the signals generated by the plurality of electrodes, wherein the plurality of electrodes, the at least one electronic circuit and the on-chip memory are all incorporated in the same monolithic arrangement, and the at least one electronic circuit is operable to process data relating to signals provided by the plurality of electrochemically responsive electrodes to derive an expiry date of the MTIC transducer.
Manufacturing a monolithic MTIC transducer with on-chip memory for expiry-date determination
Providing a monolithic structure with at least one electrode configured to generate a signal relating to a characteristic of a fluid sample, at least one electronic circuit for processing signals generated by the at least one electrode, and on-chip memory for storing data relating to signals generated by the at least one electrode, wherein the at least one electronic circuit is operable to process data relating to signals produced by the at least one electrode to determine an expiry date of the MTIC transducer.
Using organ tissue-contacting MTIC electrodes to process bodily-fluid signals and determine expiry date
Operably engaging a monolithic arrangement, which comprises at least one MTIC transducer including one or more electrochemically responsive electrodes with organ tissue of a user; processing signals generated by the at least one electrode in response to making contact with bodily fluid discharged by the organ tissue; and analyzing data relating to the processed signals by an analysis module to determine an expiry date of the MTIC transducer.
The claim set is focused on a multi-channel MTIC architecture where electrodes, on-chip signal-processing electronics, and on-chip memory are incorporated in the same monolithic arrangement, and where processed electrode signal data is used to derive or determine an expiry date. Additional independent claims cover manufacturing the monolithic MTIC structure and using organ tissue-contacting MTIC electrodes to process bodily-fluid signals while determining the expiry date via an analysis module.
