## A Novel Biologically Inspired Painless Blood Collection Method (NCSU)

- NSF Award CMMI-0402857, Mechanics and Structures of Materials
- Study of the anatomy, structure and materials of the mosquito fascicle as a model for painless a hypodermic needle
- Finite element modeling shows penetration is facilitated by a downward force together with a lateral oscillation to prevent buckling
- Results will allow for future work in polymeric micro-needle based systems and integration with MEMS devices

## Integrated Sensory Feedback for Artificial Muscles (MSU)

- NSF Award CMMI-0550651, Control Systems
- Creation of mathematical models to control precisely the displacement and force generated by artificial muscles
- Ionic polymer composites that produce bending motions at low voltages
- Integration of sensing and control for artificial muscles
- Polyvinylidene fluoride piezoelectric films for sensors
- Sensors/actuators being used for auto-injection of living Drosophila embryos for study
- Enables safe manipulation of small and delicate objects in biological studies and micro/nanofabrication

## Intensity Modulated Radiation Therapy (UFL)

- NSF Award CMMI-0457394, Service Enterprise Engineering
- New models for issues associated with Intensity Modulated Radiation Therapy (IMRT) treatment delivery efficiency and quality
- Allows for adaptive treatment planning: treatment plans adjusted daily for needs of patient
- New approach for optimal beam directions for individual treatment
- Greater options for treatment based on potential beam directions

## A Hybrid Predictive Model for Cyclic Curled Chip Formation with Serrations in Machining Using Topological Properties (UKY)

- NSF Award CMMI-0606586, Manufacturing Machines and Equipment
- Develop a mathematical model for predicting, simulating and animating the cyclic chip formation process in metal machining
- Data are being used to correlate topological (e.g. chip length, grain density) parameters to predict the quality of the product with machining variables
- Determined the change in grain boundaries by correlating the geometrical transformations during machining to the topological parameters

## Looking to the Future

- Support the ACI through research in design and manufacturing
- IWG on Manufacturing Research
- Workshops planned to energize ME & IE communities (M. Good, C.D. Mote, Jr., A. Ulsoy,...)
- Strengthen national civil infrastructure
- Workshops planned to energize CE communities (R. Luthy, G. Fenves, T. O’Rourke,...)
- Strengthen core research programs, particularly through cross-fertilization
- Provide opportunities for innovation
- Particular attention through SGER
- Investigate graduate/post doc fellowships to work in “innovation factories” (e.g., Bob Langer’s lab, George Whiteside’s lab)
- Internal discussions on research programs and directions.
