A novel gas sensor based on micro-machined ceramic hotplate and a wire-free bonding is presented, which is aim at the shortcomings of high power consumption and difficult to package existing in the current commercial ceramic gas sensors. The finite element method （FEM） is utilized to simulate the thermal characteristics of micro-hotplate and provide a theoretical
