A system is provided for integrating conformal electronics devices into apparel. The system includes a flexible substrate onto which a flexible device is disposed. The flexible device can include a stretchable coil that can be used to receive and transmit near field communications. The flexible device also includes an integrated circuit component and a memory unit. In some examples, the device also includes a sensor that is configured to record measurement of the wearer of the apparel and/or the surrounding environment.

Systems and methods for tracking a smart container are provided. The methods use sensors of the smart container to detect tampering with the smart container after the container leaves a sender and before the container arrives at a receiver. In particular, the sensors detect when the smart container has been opened by someone other than the receiver (i.e., tampered with) and write the detection of tampering (e.g., the sensor measurement) to a blockchain. Delivery agents use scanners to write their possession or agency over the smart container to the blockchain. Accordingly, the agency of the smart container can be determined if tampering occurs.

A method of incorporating a second conductor into a RFID strap device and the resulting device in multiple embodiments is disclosed. The second conductor adds functionality via coupling between the strap conductor and the second conductor. The functionality added can be a secondary antenna operating at a different frequency than the first antenna that is driven by the strap pads, a sensing capability, a drive for an emissive device such as an LED, or an interface to one or more semiconductor devices mounted onto the second conductor.

Diagnostic patches and bracelets for promoting personal and community health including related processes, methods, and systems are directed to fever patches and fever bracelets for school and university health and wellness including mitigation of the spread of infectious diseases and contact tracing during an epidemic or pandemic. Other populations addressed by these methods include nursing homes, office buildings, and factories as well as the general citizenry of entire cities, counties, states, and even countries at large. Further apparatus and devices include disease detection patches and disease detection bracelets for identifying the onset of an infection and for detecting the present of antibodies to such infectious diseases. Related mitigation and contact methods for several different addressed groups and large populations are also provided for these disease detection patches and bracelets.

A method includes receiving, by a radio frequency identification (RFID) tag, a radio frequency (RF) signal from an RFID reader. When the RF signal includes a command, the method further includes interpreting, by the RFID tag, the command to determine a field strength shell of interest. When the RFID tag is in the field strength shell of interest, the method further includes further interpreting, by the RFID tag, the command to determine a type of request, and providing, by the RFID tag, a response regarding the type of request to include one or more of a matched impedance value generated in response to the RF signal, a field strength reference current generated in response to the RF signal, and a digital value representative of an environmental condition.

A wireless sensor includes a radio frequency (RF) receiving circuit including a plurality of components, where impedances of the plurality of components establish a resonant frequency of the RF receiving circuit. The wireless sensor further includes a sensing element that when exposed to an environmental condition, affects the resonant frequency of the RF receiving circuit. The wireless sensor further includes a processing module that is operable to determine a first value for an adjustable element of a plurality of elements for a known environmental condition based on the resonant frequency and the carrier frequency, determine a second value for the adjustable element for an unknown environmental condition based on the resonant frequency and the carrier frequency, and determine a difference between the first and second values that corresponds to a change between the known environmental condition and the unknown environmental condition.

According to one aspect of the present disclosure, a device and technique for temperature detection includes a housing having a temperature detection assembly, switch circuitry, and a radio-frequency identification (RFID) module coupled to the switch circuitry. Responsive to the indicator being subjected to a temperature exceeding a threshold, the temperature detection assembly causes a change in the switch circuitry, wherein the change in the switch circuitry causes a change in a value output by the RFID module when activated.

In some embodiments, a smart card may include a substrate with a first side and a second side. A first protective layer covers the first side and a second protective layer covers the second side of the substrate. Circuitry held in the substrate includes electronic interconnects for interconnecting circuitry elements. The circuitry elements include a processor, power circuitry for powering the circuitry elements, and an environmental detection sensor for respectively detecting a predetermined environmental parameter. The processor is configured to receive an output from the environmental detection sensor, to determine from the output that the environmental detection sensor detected an environmental alert trigger condition, and to generate an alert that is representative of the environmental alert trigger condition. The protective layers include pores in a region proximate to the environmental detection sensor for exposing the environmental detection sensor to an environment around the smart card.

Technologies are shown for shipping route selection involving receiving sender and recipient shipping information for an item to be shipped and obtaining shipping route options for the item based on the sender and recipient shipping information. The route options are provided for display and selection of an option. A routing data block is created for the item at an address on a blockchain that stores shipping information for each stage of the selected route. A shipping tag is encoded with the blockchain address and attached to the item. The tag can be scanned to obtain the blockchain address and request information for a next stage of the shipping route from the block. The next shipping information from the block is received and utilized to ship the item to a next geolocation. The next shipping information can be determined based on current conditions, such as weather, pricing and availability.

A radio-frequency identification tag that includes a ground plane made of an electrically conductive material, and an actuator made of a transducer material adapted to convert a variation of a physical quantity into a mechanical displacement of the ground plane between first and second positions when the physical quantity crosses a predetermined threshold in order to indicate this event to the reader. The transducer material is a thermal shape-memory material or a magnetostrictive material or a magnetic shape-memory material. The transducer material is also an electrically conductive material. The ground plane and the actuator are both formed by a single strip made of the transducer material and a mobile portion of which moves relative to an antenna between the first and second positions when the physical variable crosses the predetermined threshold.
