Implantable RFID chips have been around for years. Since at least 2004 these devices have been capable of including GPS data, and manufacturers have been researching other measurement capabilities.
Implantable health sensors may soon be a real option with the launch by PositiveID of its ‘Wireless Body Platform’. Initially the health sensor system was designed for diabetics allowing blood sugar levels to be wirelessly read and sent to an external device. Now they have announced the ability to measure body temperature as well. The temperature sensing chip notifies people or their caregivers of rising body temperature giving them time to take anti viral medication which works best when taken early.
Three of PositiveID’s new sensors can be viewed here. Makes you wonder when chips will be able to monitor enough parameters to function as an implantable lie detector.
