Abstract: Aspects of the present disclosure relate to a sensor device having an integrated circuit and a monitoring loop coupled to the integrated circuit. The monitoring loop includes a first conductive trace and a second conductive trace, each having a first end electrically coupled to the integrated circuit and a second end. The monitoring loop includes a sterilant-responsive switch electrically coupling the second ends of the first conductive trace and the second conductive trace. The sterilant-responsive switch has a first impedance state and a second impedance state. The sterilant-responsive switch modifies an electrical connection between the first conductive trace and the second conductive trace based on exposure to an adequate environmental condition in an adequate sterilization process. The sensor device also includes an antenna coupled to the integrated circuit forming an antenna loop that is distinct from the monitoring loop.

Abstract: A bonded abrasive wheel is disclosed comprising a plurality of abrasive particles disposed in a binder, a first grinding surface, a second surface opposing the first grinding surface, and an outer circumference. The wheel comprises a rotational axis extending through a central hub and a circuit configured as a Radio Frequency Identification (RFID) unit coupled to the abrasive wheel. The circuit comprises an antenna configured to communicate with one or more external devices and comprising a first end and a second end, wherein antenna has a radius of curvature about an axis along at least a portion thereof such that the first end is disposed adjacent to but is spaced from the second end, and an integrated circuit (IC) operably coupled to the antenna and configured to store at least a first data.

Abstract: Fluid sensing devices including a layer of fluid absorption and distribution material are provided. The layer includes a porous fibrous nonwoven matrix for absorbing fluid from the object to the first major surface of the layer and laterally distributing the absorbed fluid throughout the layer and to a second major surface of the layer opposite the first major surface. Hydration sensors are disposed on the second major surface of the layer to measure a hydration level.

Abstract: Flexible, stretchable RFID tags are formed by a pocket that is formed from one or more substrates and layers of adhesive, and an electronic circuit that is located within this pocket. The RFID tags can include a stretchable substrate and an electronic circuit attached to the stretchable substrate by one or a finite number of discrete spaced apart attachment locations. When the pocket is formed by relatively thick adhesive layers adhering together one or more flexible substrates to form an internal cavity, the electronic circuit is located within this cavity and either is not adhered to any of the substrates of the cavity, and is free to move about within the cavity, or the electronic circuit can be attached to a substrate by a thin layer of adhesive.

Abstract: A shoe degradation sensor assembly includes a first sensor disposed in or proximate to a material layer of a shoe between a foot space and an outer surface of the shoe, and an electrical contact assembly operable to removably electrically connect the shoe degradation sensor assembly to a reader. The material layer changes in at least one physical property with degradation to the shoe, and the first sensor is configured to indicate the changing physical property of the material layer thereby indicating a degree of degradation to the shoe.

Abstract: A portable sensor for measuring a hydration level of an object in close physical proximity with the sensor includes a portable housing having a total volume of less than about 50 cm3. First circuitry disposed in the housing includes a thermal source, a controller electrically coupled to the thermal source, a temperature sensing element, and a processor coupled to the temperature sensing element. When the object is in close physical proximity with the sensor, the thermal source is energized by the controller with a signal having a known function of time. The object affects a time variation of a temperature of the thermal source, the temperature sensing element senses the affected time variation of the temperature of the thermal source, and the processor determines a hydration level of the object based on a characteristic of the affected time variation of the temperature of the thermal source.
