    Abstract: A mechanical frequency upconverter includes a body having a cavity. A low-frequency membrane is coupled to the body and arranged adjacent to the cavity. The low-frequency membrane is a permanent magnet or a permanent magnet is affixed to the low-frequency membrane. A high-frequency membrane is coupled to the body and arranged adjacent to the cavity. The high-frequency membrane includes a magnetic metal. Oscillation of the low-frequency membrane at a first frequency causes the high-frequency membrane to oscillate at a second frequency, which is higher than the first frequency.

    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.

    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.
