Hi All,

Prof. Keisuke Morishima, former SNF labmember from Osaka University will visit Stanford tomorrow.
He is an authority of BioMEMS and will be speaking "Emergent Functionality of Cellular Buildup Wet
Robotics", including MEMS-fabricated muscle-powered bioactuator and  biochemical energy source.
I strongly recommend to join it!

Abstract:
 We have demonstrated an environmentally robust hybrid (biotic?abiotic) robotic system that uses
living components, called “Cellular Build Up Wet Nano Robotics”. Our group has already presented
a bioactuator using rat heart muscle cells, but it is difficult to keep rat heart muscle cells
contracting spontaneously without maintaining the culture conditions carefully. By contrast, insect
cells are much robust over a range of culture conditions (temperature, osmotic pressure and pH)
compared to mammalian cells. Therefore, insect cells are more practical use of a hybrid wet robotic
system, and they can be driven without precise environmental control. From this point of view, to
utilize robust biological components as a functional systems and self assembly process and their
emergent functionality, and to build up such a soft and wet machines will lead us an innovative
fundamental change and produce a new principle and design to future man-made systems. We
demonstrate the example of a micro bioactuator and mechanical systems driven by biochemical energy.
This novel muscle-powered bioactuator successfully show autonomous beating at room temperature for
a long time without maintenance. Experimental results suggest the possibility of constructing an
environmentally robust hybrid wet robotic system with living components and open up a new science
and technology, biorobotic approach, medical, environmental monitoring, agriculture and industrial
application.
