As described above, many approaches can be taken to convert energy at small scales. This section describes some of the achievements and challenges identified in three of the most researched areas for which microfluidics are of central importance micro fuel cells, micro heat engines, and micro thrusters. The focus will be on device implementations that leverage MEMS and microfabrication technologies.
