Creating an mini electronic ignititer that can ignite lighter fluid possible?
You just need to create an electric arc that can ignite the lighter fluid.

Generally you need about 3000 / mm for electricity to jump a spark gap.  So if you had a 1mm gap, you would need 3000V, a 1/3mm gap 1000V, etc.  So the problem boils down to creating a compact high voltage generator.
