  • Publication number: 20160097028
    Abstract: The invention relates to a microfluidic device for culturing spheroids of human or animal body cells. The device can generate ample numbers (e.g., 5000) of uniform-sized spheroids, and the spheroids can be harvested for conventional biochemistry analysis (e.g. flow cytometry). In addition, the device can be used for observing the cultured samples using selective plane illumination microscopy (SPIM). In at least one embodiment, the microfluidic device incorporates a main body; a fluid channel extending inside the main body and having two inlets and an outlet open to the outside; and a plurality of chambers for culturing cell spheroids which are formed at the underneath of the fluid channel.

  • Patent number: 8887574
    Abstract: A measurement system for measuring a pressure of a fluid is provided. The measurement system includes a sensing module and a liquid electrical circuit. The sensing module includes a flexible film and a liquid electronic device. The flexible film has a first side and a second side opposite to the first side. The fluid is disposed on the first side of the flexible film, and the liquid electronic device is disposed on the second side of the flexible film. The flexible film converts the pressure of the fluid into a parameter of the liquid electronic device. The liquid electrical circuit is electrically coupled to the liquid electronic device. The liquid electronic device and the liquid electrical circuit output a measurement signal corresponding to the parameter in response to an applied electrical energy. A manufacture method of a measurement system is also provided.
