A hacker has implanted a large biometric device into his arm that can detect temperature and upload the data via Bluetooth to Android devices.
The Circadia 1.0 device was implanted into Tim Cannon's arm without anesthesia by body modification artist Steve Haworth.
Canon told publication MotherBoard Circadia could communicate with home devices that he had a "stressful day" and could "prepare a nice relaxing atmosphere" when he arrives home.
