摘要： Devices for use in cold-field emission and methods of forming the device are generally presented. In one example, a method may include providing a conductive base, dispersing carbon-filled acrylic onto the conductive base to form a conductive film, coupling a copper plate to a first side of the conductive film, and irradiating the conductive film. The method may further include dispersing carbon nanotubes (CNTs) on a second side of the conductive film to form a substantially uniform layer of CNTs, removing excess CNTs from the second side, and curing the conductive film. In one example, a device may include a polycarbonate base, a layer of carbon-filled acrylic on one side of the polycarbonate base and a layer of irradiated carbon-filled acrylic on the other, a copper plate coupled to the carbon-filled acrylic, and a substantially uniform layer of randomly aligned CNTs dispersed on the irradiated carbon-filled acrylic.

摘要： Systems and methods of harvesting and converting naturally occurring energy are described that include exposing a material to an ambient condition and harvesting at least a portion of energy that is created. Energy harvesting from fluidic and flow environments or vibration can be accomplished using types of energy harvesters, such as flexible polymers. Active materials or Electro-Active Polymer (EAP)-metal composite thin films like Ionic Polymers, Piezoceramic materials, and electromagnetic systems may be used as mechanical to electrical energy transducers. One type of an ionic EAP is ionic polymer-metal composite (IPMC), which includes a base polymer membrane that may be coated with a metal to act as a surface electrode. The surface electrode may be silver (Ag) nanoparticles. The silver nanoparticle functionalized IPMC can be used to convert mechanical vibrations and fluidic flow to electrical energy to power wireless devices and microelectronic systems, for example.

摘要： Methods and systems for sensing strain are disclosed. A thin film sensor includes a thin film polymer matrix that has two electrical terminals, conductive nanoparticles dispersed within the polymer matrix, and carbon nanotubes dispersed within the polymer matrix. The thin film sensor has a resistivity across the two electrical terminals that varies with a magnitude of strain applied to the thin film sensor. Strain may be sensed by applying a voltage to the thin film sensor, and an electrical response of the thin film sensor may be detected due to a strain present across the sensor. A magnitude of the strain can be determined based on the electrical response. Methods and systems for a memristor are also disclosed. The memristor has a resistivity that varies with a time-varying voltage input and with a time-varying strain input.

摘要： Methods and systems for identifying a strain history of a portion of a body of a patient are disclosed. The method includes measuring an electrical response of at least one thin-film sensor of a sensor apparatus that is applied to the portion of the body of the patient to obtain a reference signal. The at least one thin-film sensor includes an electrically resistant material, conductive nanoparticles dispersed substantially throughout the electrically resistant material, and conductive nano-structures dispersed substantially throughout the electrically resistant material. The electrical response of the at least one thin-film sensor is monitored to detect changes in the electrical response. Based on the changes in the electrical response, a strain history of the at least one thin-film sensor is determined. A strain history for the portion of the body of the patient is identified based on the strain history of the at least one thin-film sensor.
