Abstract
A micro-hotplate is provided in the form of a device comprising a sensor and one or more resistive heaters within the micro-hotplate arranged to heat the sensor. Furthermore a controller is provided for applying a bidirectional drive current to at least one of the heaters to reduce electromigration. The controller also serves to drive the heater at a substantially constant temperature.
