Abstract
Provided are mass and heat flow measurement sensors comprising a microresonator, such as a quartz crystal microbalance; a heat flow sensor; and a heat sink coupled thermally to the heat flow sensor. The sensors may be used to measure changes in mass due to a sample on a surface of the microresonator and also to measure heat flow from the sample on the surface of the microresonator by utilizing the heat flow sensor, which is coupled thermally to the microresonator. Also provided are methods for measuring the mass of a sample, such as a gas, and the flow of heat from the sample to the heat sink by utilizing such mass and heat flow measurement sensors.
