Wireless identification device, rfid device, and method of manufacturing wireless identification device

A radio frequency identification device comprising:

• a housing;
• circuitry in the housing configured to provide a signal to identify the device in response to an interrogation signal;
• and
• a pressable switch supported by the housing and permitting the circuitry to provide the signal to identify the device only while the switch is pressed.

A radio frequency identification device comprising:

• a housing;
• a battery in the housing having first and second terminals of opposite polarity;
• an integrated circuit in the housing configured to provide a signal to identify the device in response to an interrogation signal, the integrated circuit having a first power terminal coupled to the first terminal of the battery and having a second power terminal;
• and
• a selectively pressed switch supported by the housing and connecting the circuitry to the battery only while the switch is pressed, the switch including a first conductor formed of printed thick film and having a first end coupled to the second terminal of the battery and having a second end, a second conductor formed of printed thick film and having a first end coupled to the second power terminal of the circuitry and having a second end spaced apart from the second end of the first conductor, an insulating ring having a periphery circumscribing the second end of the first conductor and the second end of the second conductor, a diaphragm having a periphery corresponding to the periphery of the insulating ring, and having a conductive face facing the second end of the first conductor and the second end of the second conductor, the conductive face of the diaphragm being spaced apart from the first and second conductors by the insulating ring.

A radio frequency identification device comprising:

• a housing including a substrate and encapsulant over the substrate;
• a battery supported in the housing having first and second terminals of opposite polarity;
• circuitry in the housing configured to provide a signal to identify the device in response to an interrogation signal;
• and
• a selectively pressable switch formed in the housing between the substrate and the encapsulant and connecting the circuitry to the battery only while the switch is pressed.

A method of manufacturing a wireless identification device, the method comprising:

• configuring circuitry to provide a signal to identify the device in response to an interrogation signal;
• coupling the circuitry to a selectively actuated switch, such that the circuitry provides the signal only while the switch is actuated;
• and
• encasing the circuitry in a housing such that the switch is actuable from outside the housing by touching a portion of the housing.

A method of manufacturing a wireless identification device, the method comprising:

• supporting a battery on a film substrate, the battery having first and second terminals of opposite polarity;
• supporting circuitry on the substrate to provide a signal to identify the device in response to an interrogation signal;
• forming a selectively pressable switch on the substrate and coupling the switch to the battery and the circuitry to connect the circuitry to the battery only while the switch is pressed;
• and
• flowing an encapsulant over the circuitry, switch, and battery to define a housing including the encapsulant and the substrate.
