Multipolymer sensor array utilizing NFC

A method of sensing a stimulus using a sensor device, the method comprising:

• receiving, by a near field communication (NFC) circuit of the sensor device, an induced current from a mobile device using an NFC standard protocol, the induced current being used to power the sensor device;
• detecting, by a first detector circuit of the sensor device, a first stimulus;
• detecting, by a second detector circuit of the sensor device, a second stimulus;
• converting, by a sensor circuit of the sensor device, the first stimulus and the second stimulus to a first digital signal and to a second digital signal, respectively;
• and
• transmitting, by an NFC data transceiver of the sensor device, the first digital signal and the second digital signal to the mobile device using the NFC standard protocol.

A sensor device comprising:

• a detector circuit;
• a near field communication (NFC) power receiver comprising an antenna and a power management unit, the NFC power receiver configured to receive an induced current from a mobile device using an NFC standard protocol, wherein the induced current is used to operate the sensor device;
• a sensor circuit;
• an NFC data transceiver circuit;
• a non-transitory memory storage comprising instructions;
• a processor in communication with the non-transitory memory storage, wherein the processor executes instructions to:
• detect a stimulus using the detector circuit,
• convert the stimulus to a digital signal using the sensor circuit, and
• transmit the digital signal to the mobile device using the NFC standard protocol by the NFC data transceiver circuit;
• and
• a user action trigger switch, wherein the processor executes instructions to:
• enable the sensor device to detect the stimulus upon activation of the user action trigger switch, and
• disable the sensor device upon deactivation of the user action trigger switch.
