MEAM Seminar: “Soft-Matter Engineering for Robotics and Wearables”

Progress in soft lithography and soft materials integration have led to extraordinary new classes of soft-matter sensors, circuits, and transducers. These material technologies are composed almost entirely out of soft matter – elastomers, gels, and conductive fluids like eutectic gallium-indium (EGaIn) – and represent the building blocks for machines and electronics that are soft, flexible, […]

MEAM Seminar: “The Role of Manipulation Primitives in Building Dexterous Robotic Systems”

In this talk I will illustrate four different perspectives that we as a community have embraced to study robotic manipulation: 1) controlling a simplified model of the mechanics of interaction with an object; 2) using haptic feedback such as force or tactile to control the interaction with an environment; 3) planning sequences or trajectories of […]

MEAM Seminar: “Deep Learning and Uncertainty Quantification: Methodologies and Applications”

Uncertainty is ubiquitous in physical and engineering science because of the lack of knowledge, inaccuracy in measurements, objective stochastic nature. “You cannot be certain about uncertainty”. Uncertainty quantification plays an essential role in decision making, solutions of partial differential equations, optimal design, etc. However, quantifying the uncertainty is not trivial in computational science. The difficulty […]

MEAM Seminar: “Metal and Air Generate Power for Robots”

In many cases, the size and weight of energy storage technologies required to power robotic systems are too large or massive for a robot to carry, leading to limited operational times and long recharging times over which the robot remains unused. Computer-free autonomous decision making based on environmental cues provides exciting alternatives to classic control […]

MEAM Seminar: “Accelerated Design of Heterogeneous Materials for Improved Failure Characteristics”

Nature provides countless examples of the use of heterogeneity to enhance the failure properties of materials. Many biological materials, such as bone, marine shells, and fish scales, are extremely resilient to fracture and failure. These often consist of regions that are highly mineralized and stiff and regions of biopolymers that are extremely soft. In practice, […]

MEAM Seminar: “A Differential Homogenization Framework for Precipitation Strengthened Metals”

Precipitation-strengthened alloys are a commercially important class of materials because their mechanical properties can be altered by changing the microstructure through heat-treatment. Specifically, precipitates are introduced into the bulk (matrix) material to interact with dislocations and affect their mobility. It is known that the size, shape, orientation and stiffness of the precipitates, which can be […]

MEAM PhD Thesis Defense: “Controlled Levitation of Nanostructured Thin Films for Sun-Powered Near-Space Flight”

Earth’s mesosphere is the least studied part of our atmosphere. The data it contains within itself can help develop more comprehensive and accurate models of the atmosphere and can help us understand our climate better. The main challenge before scientists is the inaccessibility of this region. The pressure is not high enough for aircraft and […]

MEAM Seminar: “Exploiting Interface Patterning for Adhesion Control”

Surface force-mediated adhesion, e.g. van der Waals forces, is critical for direct bonding of bulk solids in the absence of an adhesive layer. However, no two surfaces are ideally flat or perfectly conformal due to surface roughness or intentional patterning. When in the adhered state, non-zero surface tractions arise wherever the local separation of the […]

MEAM Seminar: “Some Investigations of Phase Transitions in Rod-like Macro-molecules and Fibrous Gels”

Stress-induced solid-to-solid phase transitions form a large class of phase transitions in nature. They occur in materials that can exhibit different crystal structures under different conditions (stress and temperature), and when the stress and temperature condition changes, the material may undergo a transformation from one phase to another. Despite its considerable potential in application, some […]
