  • Patent number: 11035876
    Abstract: Provided is a sensor that is highly accurate while ensuring reduced power consumption. A sensor is an electronic circuit that includes a sensor element, an analog filter, an A/D converter, and first and second electronic circuit. The analog filter filters a waveform that includes a sensor signal from the sensor element and noise based on a servo signal. The A/D converter converts the waveform filtered by the analog filter into a first digital signal. The first electronic circuit includes a digital filter and acquires a second digital signal by performing signal processing including at least a filtering process on the servo signal by using the digital filter. The second electronic circuit acquires a third digital signal by subtracting the second digital signal from the first digital signal. A setting for the signal processing for acquiring the second digital signal is changed on the basis of the third digital signal.

  • Publication number: 20210121400
    Abstract: A sugar-responsive gel that is highly resistant to temperature changes, and a sugar-responsive drug delivery device including such a gel. The sugar-responsive gel, which comprises a gel composition including a monomer having a hydroxyl group in addition to a phenylboronic-acid-based monomer, can exhibit suitable temperature resistance. A sugar-responsive drug delivery device including such a sugar-responsive gel is less susceptible to the effects of temperature changes, and therefore can prevent undesirable excessive delivery of a drug such as insulin.
