Is it a signal or a power circuit?
If the 0.1 V is a signal, then you can use an opamp to amplify it. If you want to generate power from a low-voltage source, you can use a chopper=-rectifier to get 1.5 V from 0.1 V source.

Thank you , it is a Power circuit , What is your thoughts about the ... Joulie theif circuit would it work too ?
(Where can i find a schematic for the chopper=-rectifier? and if i can buy it from ebay can you link it for me ?
I can see that with voltage as low as 0.1 V no available semiconductor device can operate . I would suggest a mechanical chopper like relay contact to generate AC pulses, then use a transformer to get more than 1.5 V AC, then you can rectify the output. Due to the mechanical contact drive the efficiency will be low.
Another way is to use multiple low-voltage sources connected in series like in solar bateries. Voltages over 3 V can be handled by semiconductor devices with a high efficiency.
In fact, it´s an unusual voltage, and I can´t imagine what could be the source.
The only way to handle it could be stacking up in series too many cells.
