MCU controlled micro heater and thermo sensor

This medical device was designed to relieve the user from mosquito sting. The PCB employs two MuRata micro heaters to quickly heat up a ceramics plate. A Texas Instrument made thermo sensor is used to detect the change on the temperature. The overall system can finely control the temperature at the tip so that it is kept at 50 +/- 1 degrees Celsius for certain amount of time.
