Abstract
A wound dressing for wireless communication with a transceiver includes a radio-frequency antenna circuit disposed on a flexible substrate, and an electrochemical moisture sensor circuit disposed on a surface of the flexible substrate. An adhesive is provided to attach the wound dressing skin of a user. The electrochemical moisture sensor is arranged between the adhesive and the flexible substrate.
Claims19
A wireless reader for communication with a wound dressing, the wireless reader comprising:
- an antenna circuit;
- a processor operably coupled to the antenna circuit;
- and
- a memory storing instructions that, when executed by the processor, cause the wireless reader to perform a set of operations, the set of operations comprising:
- providing power to the wound dressing via the antenna circuit, thereby energizing a power module of the wound dressing;
- obtaining, via the antenna circuit and from a microcontroller of the wound dressing in circuit communication with the power module, wound dressing data for a plurality of sensors of the wound dressing, the obtaining comprising:
- selectively querying each sensor of the plurality of sensors of the wound dressing by configuring, via the microcontroller, a multiplexer of the wound dressing to selectively query each sensor from the plurality of sensors;
- and
- receiving, from the microcontroller and via the antenna circuit of the wireless reader, the wound dressing data for each selectively queried sensor of the wound dressing;
- and
- processing the obtained wound dressing data to determine a moisture content of the wound dressing.
A wireless reader for communication with a wound dressing, the wireless reader comprising:
- an antenna circuit;
- a processor operably coupled to the antenna circuit;
- and
- a memory storing instructions that, when executed by the processor, cause the wireless reader to perform a set of operations, the set of operations comprising:
- providing power to the wound dressing via the antenna circuit, thereby powering a power module of the wound dressing;
- obtaining, via the antenna circuit and from the wound dressing and from a microcontroller of the wound dressing powered by the power module, wound dressing data for a plurality of sensors of the wound dressing, wherein each sensor of the plurality of sensors is selectively queried to obtain data that forms a part of the wound dressing data by configuring, via the microcontroller, a multiplexer of the wound dressing to selectively query each sensor from the plurality of sensors and receiving, via the antenna circuit and from the microcontroller, the wound dressing data for the plurality of sensors;
- and
- transmitting, to a remote computing device, an indication of the wound dressing data.
A method for obtaining wound dressing data from a wound dressing by a wireless reader, the method comprising:
- energizing a power module of the wound dressing via an antenna circuit of the wireless reader;
- obtaining, via the antenna circuit and from a microcontroller the wound dressing coupled to the power module, wound dressing data for a plurality of sensors of the wound dressing that were each selectively queried by configuring, via the microcontroller, a multiplexer of the wound dressing, thereby generating the wound dressing data for transmission via the antenna circuit of the wound dressing;
- and
- processing the obtained wound dressing data to determine a moisture content of the wound dressing.
