Fresh results obtained by Ivan and James at Phil's lab. You can see activation and relaxation of a small bundle of skinned muscle cells (their membrane have been digested). The activation is chemically induced. The activation and relaxation solutions were exchanged manually using a pipette. We need to work on a faster and a more quite solution exchange system. We are making a few more transducers and setting up a new Mosquito prototype. Next step is to measure these forces. 

This is the experimental setup used.
