  • Publication number: 20240382097
    Abstract: This invention relates to apparatuses and methods for non-invasively measuring physiological parameters of a mammal subject using easily removable flexible electronics, and applications of the same. Specifically, a novel sensor class with a pre-curved architecture and strategically located perforations that may be used in apparatuses and methods for measuring physiological parameters of a mammal subject. Further, adhesive layers are used to attach the sensor systems on the skin of the mammal subject, and each adhesive layer is switchable chemically or physically between an adhesive state and a non-adhesive state, allowing easy removal of the corresponding sensor system from the skin of the mammal subject when being switched to the non-adhesive state.

  • Publication number: 20220167846
    Abstract: A wireless communication system has a sensor configured to detect a signal indicative of a parameter and generate sensor data as a measurement of the parameter. The sensor has a wireless communication unit configured to wirelessly transmit the sensor data over a network. The wireless communication system also has operational equipment having a central processing unit for processing data and a connection adapter configured to cause the operational equipment to receive the sensor data from the network. The connection adapter comprises a key for enabling the operational equipment to identify the sensor data.

  • Publication number: 20210386300
    Abstract: Provided are apparatuses and methods for non-invasively and continuously measuring physiological parameters of a mammal subject. The apparatus includes multiple sensor systems attached to the mammal subject, and a microcontroller unit (MCU). The sensor systems are time-synchronized and communicate with each other wirelessly and bidirectionally. Each of the sensor systems includes at least one sensor configured to detect a vital sign of the mammal subject and generate a corresponding one of the physiological parameters. The MCU is in wireless communication with the plurality of sensor systems. In operation, the MCU receives, from the sensor systems, and displays the physiological parameters of the mammal subject. The apparatus and method can be used in applications such as developing therapeutics or vaccines for a disease, or diagnosing a disease.
