WebDec 1, 2012 · A MEMS microhotplate ( Fig. 1) consists of a heating resistor embedded in a membrane anchored to a silicon rim. The membrane can either be connected to the substrate along its entire perimeter (closed-type) or by means supporting beams (suspended-type) [5]. WebAug 1, 2013 · A thin film of silica aerogel has been spin coated on silicon wafers to investigate its super thermal insulating capability. The temperature of the thin film heaters fabricated on the aerogel coated wafer is measured at different applied powers. Simulations are performed to compare the aerogel coated wafers with the micromachined wafers.
