PH.D. / RESEARCH ASSISTANT
Carbon-nanomaterial optimization
Used an electrical graphitization process (fusion) to generate covalent linkages for mechanical improvements in macroscopic carbon nanotube (CNT) networks.
-
Systematically decoupled underlying influences of fusion energy delivery and power on both graphitization and Joule heating defects in CNT yarns by tuning process parameters.
-
Demonstrated improved mechanical properties (linear strength +45%, stiffness +23%).
-
Collaborated with multidisciplinary teams to accelerate development with data mining.
-
Developed out-of-plane tearing test and characterized tearing mechanics of CNT rovings.
-
Assisted in research proposal preparation; proposal received $1.4M funding from NSF-DMREF program in 2014.
Mini scale torsional test system design
Designed torsional actuated systems to characterize CNT torsional springs
-
Built a 1 N-μm level torsion tester to measure CNT springs, saved 80% of the cost.
-
Defined torsional loading mechanics of CNT yarns for the first time.
-
Demonstrated CNT spring-enabled high energy and power density regenerative braking systems (3 kJ/kg, 1 kW/kg).
Piezoelectric actuator design
Designed a piezoelectric actuator for a resealable, ultra-low leak micro valve
-
Optimized a compact, curved PZT actuator via analytical modeling and FEA.
-
Unlocked a new actuation mechanism of curved bimorph actuators.
-
Improved displacement and force by 100% and enabled the functions of a micro valve.
