  • Publication number: 20200348121
    Abstract: A bending sensor includes a flexible substrate made of polyimide; a laser-induced graphene electrode formed into a top surface of the flexible substrate; and first and second pads formed as a laser-induced graphene into the top surface of the flexible substrate, wherein the first and second pads are in electrical contact with the laser-induced graphene electrode. A bending of the flexible substrate and the laser-induced graphene electrode changes a resistivity of the laser-induced graphene electrode, which is indicative of an amount of bending.

  • Patent number: 10768058
    Abstract: A magnetic nanocomposite device is described herein for a wide range of sensing applications. The device utilizes the permanent magnetic behavior of the nanowires to allow operation without the application of an additional magnetic field to magnetize the nanowires, which simplifies miniaturization and integration into microsystems. In addition, the nanocomposite benefits from the high elasticity and easy patterning of the polymer-based material, leading to a corrosion-resistant, flexible material that can be used to realize extreme sensitivity. In combination with magnetic sensor elements patterned underneath the nanocomposite, the nanocomposite device realizes highly sensitive and power efficient flexible artificial cilia sensors for flow measurement or tactile sensing.

  • Publication number: 20180355297
    Abstract: Nanoneedles and nanoneedle arrays and methods of making nanoneedles are provided. The methods can include multilayer fabrication methods using a negative photoresist and/or a positive photoresist. The nanoneedle arrays include one or more nanoneedles attached to a surface of a substrate. The nanoneedle can have both a proximal opening and a distal opening, and an inner passageway connecting the proximal opening and the distal opening. The nanoneedle can have a functional coating. The nanoneedle can include iron, cobalt, nickel, gold, and oxides and alloys thereof. The nanoneedle arrays can be used for the administration and/or the extraction of agents from individual cells. In one or more aspects, the nanoneedles can be magnetic nanoneedles. An oscillating magnetic field applied to a magnetic nanoneedle can induce one or both of heating and vibration of the magnetic nanoneedle. The heating and/or vibration can cause a magnetic nanoneedle to penetrate the wall of a cell.

  • Patent number: 9768888
    Abstract: A passive and wireless sensor is provided for sensing at least one of magnetic field, temperature or humidity. The sensor can provide only one of the sensing functions, individually or any combination of them simultaneously. It can be used for various applications where magnetic field changes, temperature and/or humidity need to be measured. In one or more embodiments, a surface acoustic wave (SAW) sensor is provided that can measure one or more of a magnetic field (or current that generates the magnetic field), temperature and humidity. In one or more embodiments, a magnetoimpedence (MI) sensor (for example a thin film giant magnetoimpedance (GMI) sensor), a thermally sensitive (for example a Lithium Niobite (LiNbO3)) substrate, and a humidity sensitive film (for example a hydrogel film) can be used as sensing elements.

  • Publication number: 20130337034
    Abstract: Magnetic nanowires can be used as an alternative method overcoming the limitations of current cancer treatments that lack specificity and are highly cytotoxic. Nanowires are developed so that they selectively attach to cancer cells via antibodies, potentially destroying them when a magnetic field induces their vibration. This will transmit a mechanical force to the targeted cells, which is expected to induce apoptosis on the cancer cells.
