MEAM Seminar: “Microscale Robotic Wetware for Synthetic Biology”

Moore 216 200 S. 33rd Street, Philadelphia, PA, United States

Small-scale robotic systems have emerged as promising tools to perform a wide-range of tasks in microbiology and medicine such as targeted delivery, cell manipulation, environmental monitoring, and microassembly. In order to perform these tasks, the robot must execute precise locomotion, take measurements from its environment, and use those measurements to make decisions. However, unlike their […]

MEAM Seminar: “From Elder Care Service Robots to the Design of Low-Cost End-Effectors and Novel Manipulation Techniques”

Room 337, Towne Building 220 South 33rd Street, Philadelphia, PA, United States

Older adults are forming a much larger percentage of the population leading to a strain in the healthcare sector. It is expected that the population aged 65 and over in the United States alone will double in the next 30 years, and similarly worldwide. Despite abundance of the facilities to accommodate the growing older adult […]

MEAM Seminar: “Mechanical Models for DNA”

Room 337, Towne Building 220 South 33rd Street, Philadelphia, PA, United States

We will discuss two complementary mechanical models for DNA that deal with, respectively two problems: one, phase transitions in a DNA molecule, and two, allosteric interactions between two ligands bound to DNA. Experimental studies on single molecules of DNA have reported a rich variety of cooperative structural transitions, including coexistence of three phases, when a […]

MEAM Doctoral Dissertation Defense: “Additive Manufacturing and Mechanical Properties of Cellulose Nanofibril Materials”

Room 337, Towne Building 220 South 33rd Street, Philadelphia, PA, United States

Cellulose nanofibrils (CNFs) are a nanomaterial derived from plants that have high specific stiffness and strength, can be made into optically transparent materials, and are biodegradable. These properties make CNFs an attractive building block for bulk structural materials. However, CNFs are typically produced in aqueous suspension at low CNF weight fractions (<1 wt.%), which makes […]

MEAM Seminar: “Delivering Expressive and Personalized Fingertip Haptic Cues”

Room 337, Towne Building 220 South 33rd Street, Philadelphia, PA, United States

The importance of meaningful tactile experiences has become increasingly apparent in areas such as teleoperation, education, and gaming. As the applications of rendering haptic stimuli are growing, so are the requirements of haptic interfaces, in that the intended audience is becoming more diverse and the intended interactions are becoming more complicated. For the past few […]
