Futuristic Bluetooth Band-Aid concept for paramedics

This concept Bluetooth Band-Aid by Indian designer Saravanan Nagasundaram can do good in case of accidents. When these Bluetooth Band-Aids are stuck to the victims, the BT-BA reads the data from the personal tag, including blood type and allergies. All the retrieved data is displayed on the small screen. Other than that, The Band-Aid also features a color indicator that shows that how serious a patient is. The ‘capsule’ can check for the patient’s blood sugar level and can inject insulin if necessary. The concept is indeed appreciable but as we all know a concept is just a concept, so it would be better if we look for some other good alternative.
