  • A MICROFLUIDIC SENSOR
    Publication number: 20230404777
    Abstract: A microfluidic sensor comprising: a first substrate; a second substrate; a cavity formed between the first substrate and the second substrate, the cavity comprising a reservoir portion and a channel portion extending from the reservoir portion; a capacitive element disposed between the first substrate and the second substrate, the capacitive element being at least partially disposed in the channel portion of the cavity; and a dielectric sensing liquid provided in the reservoir portion. Upon application of a force to the first substrate adjacent the reservoir portion, the reservoir portion is configured to deform and displace the sensing liquid along the channel portion, so as to change the capacitance of the capacitive element within the channel portion.

  • Cylindrical and spherical triboelectric generators
    Patent number: 9843275
    Abstract: A generator includes a first member, a second member and a sliding mechanism. The first member includes a first electrode and a first dielectric layer affixed to the first electrode. The first dielectric layer includes a first material that has a first rating on a triboelectric series. The second member includes a second material that has a second rating on the triboelectric series that is different from the first rating. The second member includes a second electrode. The second member is disposed adjacent to the first dielectric layer so that the first dielectric layer is disposed between the first electrode and the second electrode. The sliding mechanism is configured to cause relative movement between the first member and the second member, thereby generating an electric potential imbalance between the first electrode and the second electrode.
