Abstract:
Medical devices configured for in vivo assays of one or more analytes can sometimes be problematic if left inserted in a tissue, such as skin, for an extended time. Certain medical device surface profiles may aid in alleviating this issue. Accordingly, medical devices may comprise a base surface having a tissue-facing surface profile defined thereon, and a sensor extending through the base surface and at least a portion of the tissue-facing surface profile. The tissue-facing surface profile deviates from the base surface, and the tissue-facing surface profile is also configured to undergo a change in shape, hardness, or a combination thereof after contacting a tissue for a length of time. A dynamic material may be present in at least a portion of the tissue-facing surface profile.
Abstract:
Systems, methods, apparatus and devices are described for monitoring a property of an object or an individual, using a conformal sensor device that substantially conforms to contours of a portion of a surface of the object or the individual. The measurement includes data indicative of a property of a temperature of the portion of the surface and the degree of the conformal contact. An analysis engine is used to analyze the data and to generate at least one parameter indicative of the property of the temperature. Based on a comparison of the at least one parameter to a preset threshold, at least one alert can be issued and/or a command can be transmitted to regulate an environmental condition. The at least one alert can be indicative of a potential risk of harm to the object or individual.
Abstract:
The invention relates to diagnostic devices, which are capable of characterising gases and other volatile organic compounds (VOCs) present in the gastrointestinal tract, for diagnosing diseases. The invention extends to apparatuses for use in the in vivo detection and characterisation of gases and VOCs, and to methods for diagnosing diseases.
Abstract:
This document relates to methods and materials involved in detecting neurochemical signals, electrophysiological signals, ions, or combinations thereof with brain tissue. For example, methods and materials for using probes to detect neurochemical signals (e.g., neurotransmitter concentrations), electrical signals, or combinations thereof during deep brain stimulation are provided.
Abstract:
An apparatus for measuring a characteristic of a body part, such as an infant's head, includes a flexible substrate, a plurality of sensing elements provided along the substrate, and an electronic system. Each of the sensing elements (i) has a component wherein an electrical characteristic of the component changes predictably in response to the component being bent, and (ii) provides a signal that is indicative of the current value of the electrical characteristic. The electronic system is structured to receive the signal of each sensing element and determine a measure of a degree of curvature of the sensing element based on the received signal. The electronic system is also structured to determine, based one or more of the measures, a representation of a curvature of a segment, such as a loop, defined by a selected one or more of the sensing elements.
Abstract:
A biosensor fabrication process comprising transferring one or more layers (e.g., conductive ink and/or membrane layers) from a surface to the biosensor substrate and biosensors produced therefrom. Layers are transferred from the surface to the biosensor substrate using a deposition device, such as a pick and place machine or a printing pad/plate.
Abstract:
The present disclosure is directed to a wearable garment device for application of electrical current to a patient's tissue. The garment device includes a material having a aperture and a mesh material extending across the aperture. At least one electrode is attached onto one side of the mesh material. The surface of the mesh material attached to the at least one electrode is defined as the outer surface. The other surface of the mesh material is defined as the inner surface. The inner surface of the mesh material is placed against the patient's tissue to receive the electrical stimulation from the electrode.
