Abstract:
Systems and methods are provided for extracting hemodynamic information, optionally employing portable electronic devices with optional User Interface (UI) features for system implementation. The systems and methods may be employed for acquiring hemodynamic signals and associated electrophysiological data and/or analyzing the former or both in combination to yield useful physiological indicia or results. Such hardware and software is advantageously used for non-invasively monitoring cardiac health.
Abstract:
Features for rechargeable lithium ion batteries, the batteries optionally employing vertically aligned carbon nanotube scaffolding, are described. Methods of manufacture and a solid polymer electrolyte are described for 3-dimensional battery architectures using the vertically aligned carbon nanotubes. Poly(ethylene)oxide bis(azide) and graphene poly(lactic acid) composite coatings are also described for use in such batteries or others.
Abstract:
Hardware and software methodology are described for a non-invasive approach to blood pressure measurement in pulmonary artery and systemic arteries by using wall displacement and blood velocity that are measured using ultrasound, microwave techniques and/or other radiofrequency (RF) techniques.
Abstract:
A method of fabricating a graphene oxide material in which oxidation is confined within the graphene layer and that possesses a desired band gap is provided. The method allows specific band gap values to be developed. Additionally, the use of masks is consistent with the method, so intricate configurations can be achieved. The resulting graphene oxide material is thus completely customizable and can be adapted to a plethora of useful engineering applications.
Abstract:
A toroidal plasma is generated without voltage input. It can be produced using a pressurized water jet directed at a non-conductive, dielectric plate. Systems and methods employing the setup are described in which energy is generated and optionally harvested in addition to corona light.
Abstract:
Efficient methods for producing a superhydrophobic carbon nanotube (CNT) array are set forth. The methods comprise providing a vertically aligned CNT array and performing vacuum pyrolysis on the CNT array to produce a superhydrophobic CNT array. These methods have several advantages over the prior art, such as operational simplicity and efficiency.
Abstract:
The present invention relates to a nano-enhanced device for substance transfer between the device and a tissue. The device comprises a substrate with substantially aligned carbon nanotubes anchored within the substrate, and with at least one end of the carbon nanotubes protruding from the substrate. The protruding nanotube ends may be coated with a drug for delivery of the drug into body tissue. The present invention may be incorporated into an angioplasty catheter balloon or into a patch that is worn on the skin. The carbon nanotubes can be grouped in clusters to effectively form nano-needles which can transfer fluid to or from the subdermal tissue. The nano-needles can be used in conjunction with a sensor to ascertain body fluid information such as pH, glucose level, etc.
Abstract:
Carbon nanotube needles and needle arrays are described in which the precursor pillars are etched by oxygen plasma treatment to provide tapered and/or sharp-tip needles. Processes, products by process, and devices incorporating the sharp-tip needles are further described.
Abstract:
Connecting mechanisms between medical device or other physical components are described. One or more plug pin connector(s) is received in a matching socket connector(s) to either permanently or temporarily join at least two components together along with associated components. Each plug connector is associated with a releasable pull line to facilitate such assembly.
