  • Patent number: 11162934
    Abstract: A sensing chip attached to a bandage monitors the healing process of a wound by detecting growth factors, thrombin and fibrinogen. The complementary metal-oxide semiconductor includes a functionalized working electrode, functionalized counter electrode and functionalized reference electrode. The healing progress is stimulated by generating oxygen in the wound.

  • Patent number: 11134870
    Abstract: A device detects infection associated with a prosthetically implanted device, such as a prosthetic knee. The device includes a sensor to detect the presence of one or more proteins secreted by body tissues in response to infection. The sensor may include a surface with a molecular imprint of the protein connected with a potentiometric or amperometric measuring device to detect when the protein bonds with the implanted surface. The device further includes an inductive coil coupled with a corresponding coil located outside the body. Electrical power for operating the measuring device and other circuitry is provided by inductive coupling between the coils. Signals indicating whether the protein is detected are communicated from the device to the external circuitry connected with the external coil.

  • Patent number: 11123022
    Abstract: A blood pressure estimating apparatus includes a sensor configured to obtain a bio-signal of an object; and a processor configured to extract a first cardiovascular feature and a second cardiovascular feature based on the bio-signal, and estimate blood pressure based on a first changing tendency of the first cardiovascular feature from a first reference level and a second changing tendency of the second cardiovascular feature from a second reference level, the first changing tendency and the second changing tendency being independent from each other.

  • Patent number: 11122984
    Abstract: A pulse wave detecting device includes a sensor section and a control unit. The sensor section is rotatable about a first axis and is rotatable about a second axis. The control unit determines a rotation angle about the second axis and a rotation angle about the first axis in a state where the sensor section is pressed against the body surface with a prescribed pressing force. After determining the optimal roll angle and the optimal pitch angle, the control unit reduces the pressing force to a reset value smaller than the prescribed pressing force and larger than zero, increases the pressing force from this state, detects a pulse wave based on pressure signals detected by pressure detecting elements during the increase, and calculates vital information based on the detected pulse wave.

  • Patent number: 11116411
    Abstract: A pulse wave detecting device includes a sensor section and a control unit. The sensor section is rotatable about a first axis and is rotatable about a second axis. The control unit determines a rotation angle about the first axis, and determines a rotation angle about the second axis in a state where a pitch angle of the sensor section is controlled to the optimal pitch angle. Then, in a state where the sensor section is controlled to the optimal roll angle and the optimal pitch angle, the sensor section is pressed against the body surface, and a pulse wave is detected in this state based on pressure signals detected by pressure detecting elements, and vital information is calculated based on the detected pulse wave.
