  • Patent number: 11156633
    Abstract: An AFM that suppress parasitic deflection signals is described. In particular, the AFM may use a cantilever with a probe tip that is offset along a lateral direction from a longitudinal axis of torsion of the cantilever. During AFM measurements, an actuator may vary a distance between the sample and the probe tip along a direction approximately perpendicular to a plane of the sample stage in an intermittent contact mode. Then, a measurement circuit may measure a lateral signal associated with a torsional mode of the cantilever during the AFM measurements. This lateral signal may correspond to a force between the sample and the probe tip. Moreover, a feedback circuit may maintain, relative to a threshold value: the force between the sample and the probe tip; and/or a deflection of the cantilever corresponding to the force. Next, the AFM may determine information about the sample based on the lateral signal.

  • Publication number: 20210030958
    Abstract: Aspects provide fluid responsive actuators and methods of using fluid responsive actuators capable of generating a power-to-volume ratio sufficient to inject a drug from a syringe within an injection period from about 1 to about 60 seconds after exposure of the fluid responsive elements to a fluid. The fluid responsive actuators can be used to inject viscous drugs to a patient.

  • Patent number: 10415550
    Abstract: Evaporation-driven engines are disclosed herein. An example engine can include a water source having a high humidity zone proximate the surface of the water source, a supporting structure, and a hygroscopic material disposed on the supporting structure and configured to generate mechanical force in response to a changing relative humidity. The hygroscopic material can be repeatedly exposed to the high humidity zone and removed from the high humidity zone thereby causing the hygroscopic material to generate mechanical force.

  • Publication number: 20190178233
    Abstract: A method and system for providing an engine for producing mechanical energy through the absorption and evaporation of moisture uses a hygroscopic material in one or more configurations to do mechanical work. The hygroscopic material can include microbial spores, plant cells and cell materials, silk and hydrogel materials that absorb moisture and expand or swell when exposed to high relative humidity environments and shrink or return to nearly their original size or shape when exposed to low relative humidity environments wherein the moisture evaporates and is released. By exposing the hygroscopic material to a cycle of high relative humidity environments and low relative humidity environments, useful work can be done. One or more transmission elements can be used to couple the hygroscopic material to a generator that converts the mechanical energy to, for example, electrical energy.
