Abstract:
An electrode (1) suitable for implantation in a body, for recording electrical signals from nervous tissues in the body and for electrically exciting nervous tissues in the body, is disclosed. The electrode (1) comprises a communication channel (11) for communicating signals to and /or from the body, and a support (3) for supporting the or each communication channel (11), such that the length of the communication channel (11) is greater than the distance between the its ends. The communication channel (11) may be flexible such that changes in the distance between the ends of the communication channel (11) can be accommodated. An anchor portion (9) anchors at least a portion of the electrode (11) to surrounding material when implanted in the body.
Abstract:
An implantable sensor for use in measuring a concentration of an analyte such as glucose in a bodily fluid, including a body (11) with a sensing region (114) adapted for transport of analytes between the sensor and the bodily fluid. The sensing region (114) is located on a curved portion of the body (116) such that when a foreign body capsule forms around the sensor, a contractile force (112) is exerted by the foreign body capsule toward the sensing region (114). The body is partially or entirely curved , partially or entirely covered with an anchoring material for supporting tissue ingrowth, and designed for subcutaneous tissue implantation. The geometric design, including curvature, shape, and other factors minimize chronic inflammatory response at the sensing region and contribute to improved performance of the sensor in vivo.
Abstract:
A wearable electronic patch with an enhanced radio antenna includes an antenna, radio circuitry, a base portion, a distal portion, and intermediate portion, and a spacer, configured to raise the antenna away from the base portion, and thus away from a wearer to improve radiation properties of the antenna. The spacer may be sized and shaped to expand from a compressed state, as it may be when the patch is packaged, to an expanded state that raises the antenna when it is applied to a wearer. Other aspects, embodiments, and features are also claimed and disclosed.
Abstract:
Embodiments of the present disclosure provide techniques and configurations for an orthotic device. In one instance, the device may include an orthotic device body and at least two sensors spatially disposed inside the orthotic device body. A first sensor may provide a first output responsive to pressure resulting from application of mechanical force to the orthotic device body. A second sensor may provide a second output responsive to flexing resulting from the application of mechanical force to the orthotic device body. The device may also include a control unit communicatively coupled with the sensors to receive and process the outputs provided by the sensors in response to pressure and flexing. Other embodiments may be described and/or claimed.
Abstract:
Physiological monitoring can be provided through a wearable monitor (12) that includes a flexible extended wear electrode patch (15) and a removable reusable monitor recorder (14). A pair of flexile wires (61, 71) is interlaced or sewn into a flexible backing (20), serving as electrode signal pickup and electrode circuit traces. The monitor (12) sits centrally on the patient's chest along the sternum (13), which significantly improves the ability to sense cutaneously cardiac electric signals, particularly those generated by the atrium. To counter the dislodgment due to compressional and torsional forces, non-irritating adhesive (43) is provided on the underside, or contact, surface of the electrode patch (15), but only on the distal (30) and proximal ends (31). Interlacing the flexile wires (61, 71) into the flexile backing (20) also provides structural support and malleability against compressional, tensile and torsional forces.
Abstract:
An implant device (500) for creating a neural interface with the central nervous system having a polyimide-based electrode arra (520) is presented along with a method for making the device. The device may be configured as a three dimensional structure (600) and is capable of sensing multi-unit neural activity from the cerebral cortex. Mechanical, electrical and biological characteristics of the device support it use as a reliable, long term implant.
Abstract:
A bi-stable sensor is provided that includes a frame upon which electrical and optical components may be disposed and a coating, such as an overmold coating, provided about the frame. A resistance-providing component is provided integral with or external to the coated bi-stable sensor such that the bi-stable sensor has two mechanically stable configurations that may be transitioned between by overcoming the resistance provided by the resistance- providing component and/or the by the coating, hi one embodiment, the resistance-providing component comprises an elastic band provided about a hinge of the frame, either within or external to the coating, hi one embodiment, the sensor may be placed on a patient's finger, toe, ear, and so forth to obtain pulse oximetry or other physiological measurements.
Abstract:
The invention relates to a sensor device for detecting biometric characteristics, especially fingerprint minutiae. According to the invention, a positive engaging load compensation device is provided between a flexible conductor strip (8) and a chip housing (3).
Abstract:
Apparatus are provided for monitoring a condition of a surface based on a measurement of a property of the surface using a sensor. In an example, the property is performed using an apparatus disposed above the tissue, where the apparatus includes at least one coil structure formed from a conductive material, at least one other component, and at least one cross-link structure physically coupling a portion of the at least one coil structure to a portion of the at least one other component, the at least one cross-link structure being formed from a flexible material. The at least one other component can be a sensor component or a processor unit.
