  • Publication number: 20210015402
    Abstract: Design and development of an affordable, user-friendly, and portable POCT hand tremor detection device has been reported. This device is composed of a detection unit, a flexible pressure sensor, a signal processing unit, and a power supply. The detection unit is composed of the sensor and press-knob. The flexible pressure sensor is a combination of usually spaced apart flexible polymer preferably polydimethylsiloxane, flexible substrate preferably paper, and a conductive coating preferably reduced graphene oxide (RGO). When the users put pressure on the press-knob through the fingers, the flexible pressure sensor actuates and bends so that conductive RGO layers on the flexible substrates come in contact with each other to generate an output current.

  • Publication number: 20200336164
    Abstract: The present invention relates to a portable, affordable and user-friendly mobile RF radiation detection device. The device is composed of three major parts, namely, a sensor arrangement, a processing 5 unit, and a power supply. The sensor arrangement consists of a flexible sensor and an associated circuit element having few passive electrical components. The substrate of the sensor was made of nanoparticle treated flexible material preferably paper treated with the gold nanoparticles (AuNPs). The electrically conducting patches made 10 of conductive materials preferably silver pastes on the substrate are the key component in detecting the RF radiation from the mobile. The electrical signal generated by the RF sensor is sent to the processing unit, which further transmitted the signal to a mobile android application for displaying the result.

  • Publication number: 20200323461
    Abstract: The present invention discloses a low-cost, user-friendly and portable point-of-care system for detection of physical stress at different parts of body of a human subject. The prototype comprises a sensor arrangement, a processing unit, and a power supply. The sensor arrangement consists of a flexible and soft substrate preferably made of electrically conducting layer coated polymer facilitating detection of electric field potential of a part of a living body of the human subject such as finger-tip, tip-toe, wrist, or tongue, once they come in contact with said sensor arrangement. The sensor arrangement generates an electrical signal, which can be correlated to the stress level of the body parts at a very high-precision. The electrical signal generated by the sensor arrangement is sent to the processing unit, which may be further transmitted wirelessly to a mobile android application for the display of the results.
