CBE Doctoral Dissertation Defense: “MEMS-Based Electrochemical Power Sources for Extended Operational Duration of Micro Unmanned Vehicles” (Yanghang Huang)

Room 221, Singh Center for Nanotechnology 3205 Walnut Street, Philadelphia, PA, United States

Abstract: Micro unmanned vehicles, defined as 25-gram to 5-kg in weight, are increasingly being utilized in applications such as search and rescue or agricultural monitoring. Such vehicles are typically powered with lithium-ion batteries. However, vehicle operational efficiency and capability are often compromised by the limited energy density of these batteries, resulting in short operational duration. […]

MEAM Ph.D. Thesis Defense: “Multi-Robot Coordination and Cooperation via Graph-Based Computation”

Levine 307 3330 Walnut Street, Philadelphia, PA, United States

Multi-robot coordination and cooperation are critical behaviors that improve team performance and enable new tasks in application areas like autonomous construction, agriculture, and extended operation in large unknown regions. This dissertation examines these behaviors in the context of the multi-robot resource allocation problem, where robots must be allocated to regions of demand. In particular, we […]

ESE PhD Thesis Defense: “Aluminum Scandium Nitride Ultra-Wideband Resonator and Filter Systems”

Room 35, Singh Center for Nanotechnology 3205 Walnut Street, Philadelphia, PA, United States

Aluminum scandium nitride (AlScN), a ternary alloy by doping scandium into aluminum nitride (AlN), has circumspectly gained recognition through the last decade as one of the promised materials in forming the next generation radio frequency (RF) filters and resonators - core components in the wireless telecommunication systems that interconnect today’s world. This, coupled with the […]

MEAM MSE Thesis Defense: “Algorithmic Design of an Origami Squirrel-Inspired Paw for Quadrupedal Locomotion in Bar-like Terrains”

Levine 307 3330 Walnut Street, Philadelphia, PA, United States

The Dynamic Origami Quadruped (DOQ), an origami quadrupedal robot, has been primarily utilized for hopping and walking on flat ground. However, adapting it walking on bar-like terrains presents significant challenges. Inspired by the Squirrel-inspired Rapid Tenodesis (SQRT) foot which is capable of passively grasping onto curved surfaces during perching, this thesis explores the integration of […]

ESE Ph.D. Thesis Defense: “Integrating graphene Hall sensors with co-designed silicon circuits for high-throughput magnetic biosensing”

Auditorium, LRSM Building 3231 Walnut Street, Philadelphia, PA, United States

The limitations of silicon electronic devices increasingly constrain the performance of silicon integrated circuits (ICs) and their use in new applications. Next-generation devices with exceptional performance and new functionalities have been realized using two-dimensional materials such as graphene. For example, graphene Hall-effect sensors (GHSs) greatly outperform commercial silicon magnetic-field sensors and could significantly improve the […]

BE Doctoral Dissertation Defense: “Nanoparticle-based RNA therapeutic strategies for treating multiple myeloma” (Christian Figueroa-Espada)

Heilmeier Hall (Room 100), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

The Department of Bioengineering at the University of Pennsylvania and Dr. Michael J. Mitchell are pleased to announce the Doctoral Dissertation Defense of Christian Figueroa-Espada.

MEAM Seminar: “Bio-inspired Architected Materials/Structures with Enhanced Failure Characteristics”

Heilmeier Hall (Room 100), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

Structural failure is a critically important design consideration in many engineering applications. Nature provides a number of interesting examples of lightweight structural features that exhibit outstanding failure characteristics. Recent progress in additive manufacturing has facilitated precise control over geometric features, allowing for the implementation of bio-inspired structural designs on a layer-by-layer basis. In this talk, […]

MEAM/MSE Special Seminar: “Starfish-Inspired Tubefeet for Temporary Underwater Adhesion”

Towne 227 (MEAM Conference Room) 220 S. 33rd Street, Philadelphia, PA, United States

Temporary and switchable underwater adhesion plays an important role in robotic underwater locomotion and transportation. The physical features of the suction cups of octopuses have been mimicked, where the vacuum chamber formed by the deformation of these cups enable strong adhesion. However, the works mainly focused on the strength of the underwater adhesion. For the […]

BE Doctoral Dissertation Defense: “Remote control of cell function using temperature as an input” (William Benman)

Berger Auditorium (Room 13), Skirkanich Hall 210 South 33rd Street, Philadelphia, PA, United States

The Department of BIoengineering at the University of Pennsylvania and Dr. Lukasz Bugaj proudly announce the Doctoral Dissertation Defense of WIlliam Benman. Title: Remote control of cell function using temperature as an input Advisor: Lukasz Bugaj Date: Wednesday, July 24, 2024 Time: 10:00AM EST Location: Skirkanich Hall, Berger Auditorium, Rm. 013 Zoom option: https://upenn.zoom.us/j/91967695550 The public […]
