A Novel Biologically Inspired Painless Blood Collection Method (NCSU)  NSF Award CMMI , 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 , 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 , 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 , 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 25 0 C Chip formation process Temperature field C Process Variables Cyclic Curled Chip Formation Increasing Feed

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.
