  • 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.

  • NXPs MiFare chips are used in numerous RFID transport card systems around the world. The cryptography on its MiFare Classic chips was cracked by researchers from Radboud University last year, while working exploit code was published by a German researcher in October.

    NXP security architect Jan Brands told ZDNet UK that transport operators had been "worried" about the cracks, and had started to move up to other chips in the MiFare family.

    "Systems operators were worried about the security of MiFare Classic. The systems are made to be upgraded to provide better security," said Brands. "When access gates need to be upgraded, they can be upgraded so they accept MiFare Classic and MiFare Plus cards."

    The picture shows an upgrade system developed by NXP to demonstrate that transport operators can use both types of card with the same gate, by issuing MiFare Plus cards with MiFare Classic compatibility.

  • NXP is researching smart-metering technology that consumers can use to monitor their energy consumption.

    The smart meter is at the bottom right of this device, which can provide two-way monitoring of electricity consumed and of energy sold back to the grid. The energy returned to the grid is produced by the consumer via solar panels or wind turbines.

    Electricity companies also have the option to remotely disconnect the power supply if the consumer has not paid energy bills.
