 | Biological haircells are highly sensitive and yet robust mechanoreceptors that can respond to an extremely wide variety of physical, fluidical, and chemical stimulus. The variety of animals that use haircell, a simple mechanical transducer, for critical tasks is astonishing. This projected aimed to: (1) Learn from the biological systems about haircell sensor design, materials, and performance, and the way multiple sensors are organized; (2) Develop artificial haircell sensors that are ... |

| We purchased an InfraScope II thermal imaging microscope from Quantum Focus Instruments Corporation. The machine was purchased within a month after receiving the DURIP funds, and was installed in the Micro and Nanotechnology Laboratory. The total cost of the QFI InfraScope II Infrared Imaging Microscope is $129,540 (charged to the core account) plus $23,373, charged to a match account provided by the Electrical and Computer Engineering Department of the University ... |

| We have developed new designs and fabrication techniques for arrayed (one dimensional and two dimensional) DPN probes in two categories, passive probes and active probes. We have successfully developed mechanical and electrical interfaces to commercial AFM machines and software. Arrayed DPN writing has been achieved. As a highlight, a set of ten different characters has been written using ten different pens in one single run. We also have significantly advanced ... |

| Fast and efficient Computer Aided Design (CAD) tools for microfluidic components and systems were developed in this effort. Innovative numerical methods and algorithms for mixed-technology simulation of microfluidic devices and systems are described. Algorithms and techniques for coupled circuit/device modeling of microfluidic systems are presented. Test structures and devices were fabricated, and measurements taken to enable the computational prototyping of microfluidics and Micro-Electro Mechanical Systems (MEMS). |
