Abstract: The present disclosure provide a detection device of microfluidic polymerase chain reaction (PCR) and a detection system including the same. This all-in-one device and system may be used to detect at least one biological detection chip, so that can amplify gene fragments at the front-end and detect them at the back-end immediately, decreasing the time required for the analysis, enabling real-time, low-cost, and rapid detection of various viruses, such as EBV and COVID-19, without compromising accuracy or sensitivity.

Abstract: A triboelectric nanosensor includes an elastic body, a liquid metal and a wire. The elastic body includes an inner wall surrounding a chamber, and a plurality of biomimetic shark placoid scale-shaped microstructures adjacent to each other and disposed at at least one portion of the inner wall. The liquid metal is located within the chamber and surrounded by the elastic body. The wire is electrically connected to the liquid metal. The elastic body is pressed to be deformed and restores to change a contact state between the liquid metal and the biomimetic shark placoid scale-shaped microstructures, thereby allowing a plurality of electrons to flow into the liquid metal via the wire or to flow out from the liquid metal via the wire.

Abstract: An air mattress includes a first air cell, a second air cell, a plurality of third air cells, and a body-lifting air cell. The second air cell includes a first air chamber, a second air chamber, and a structurally-weakened region. The body-lifting air cell is below the second air cell and at least one of the third air cells. The body-lifting air cell is inflated by an air source controlled by a control system. When the body-lifting air cell is inflated, a vertical distance between the top of second air cell and the bottom of air mattress is greater than a vertical distance between the top of first air cell and the bottom of air mattress. When the body-lifting air cell is inflated, the second air cell has a lower structural strength than the other air cells to have a cushioning effect against external forces.
