PCM – Week 09. final project idea

Although nothing has been decided for my final project yet to be specific, I wants to use bacterial cells. Around an environment with moisture (water) around some special bacterial cells, the cells can cause plastic tape or paper with them to bend under the influence of moisture.
In other words, by using the movement of moisture-induced bacteria as a new power source, I want to make something physical stuffs like moving wheel or making light on LED.
I’m looking for a possible place to make it as I need to access to the biomaterials.
