Here is a smart bandage that can monitor the body and report data to a mobile device via Bluetooth BLE, WiFi, RFID, or NFC. The readings are logged and graphed over time to identify trends. The care provider can establish parameters for out-of-bound conditions.
WINDGO was recently granted patent for this wearable device. As the company explains:
Smart bandages will allow the user to receive preprogrammed or adaptive therapeutic stimulus and medication directly from the bandage’s smart response module. The health module within the smart bandage will alert a network module such as a mobile device of any readings that may indicate a need for adjustments to medication dosages. The correct dosages are then delivered on a scheduled basis or event trigger dispensed automatically to the body.
