This smart-bandage strip has sensors which make frequent measurements of pressure and humidity. The pressure of the bandage can be monitored to make sure it is not too loose or tight, while humidity readings can tell a clinician if a wound is bleeding or suppurating.
The strip has two pressure sensors and one humidity sensor, plus a wireless link to a USB dongle. The dongle can be plugged into a computer to take readings from the sensors.
The strip also contains a flexible printable battery, which means patients can move easily while wearing it.
The readings can be taken offline, and then uploaded when a patient comes back in range of the dongle.
At the time of writing, the strip was not a working prototype, but was due to be within a matter of days. The working prototype is the PCB pictured above the strip, which has a flexible antenna and pressure sensors.
