Micro Scalable Thrusters for Adaptive Mission Profiles in Space
The Problem: State-of-the-art electrospray-based micro-propulsion thrusters for Cubesats are designed around arrays of sharp micro-emitters protruding directly into space. These emitters are responsible for generating the intense electric fields needed to electrospray a propellant and generate thrust. Sharper emitters require lower voltages to operate,... (read more) -
Energy-Efficient and Scalable Access Scheme for Non-Volatile Memory Devices
The Problem:CMOS memory technology is plagued by scaling issues such as oxide aging, capacitive coupling, and cell-to-cell interference. Non-volatile memory (NVM) devices like memory resistors (memristors) offer increased power efficiency and reduced chip area, allowing them to emerge as a viable alternative. As more and more NVM devices are used in... (read more) -
A Charge Pump Gate Drive for SiC MOSFETs to Reduce Switching Losses
The Problem:Compared to other transistors, silicon carbide (SiC) MOSFETs have improved properties due to lower conduction loss and specific capacitance and higher switching speed and maximum junction temperature. However, high turn-on switching losses due to lower transconductance remains a problem; thus, it is still difficult to implement SiC MOSFETs... (read more) -
Low-Density Syntactic Foam for Material Extrusion Additive Manufacturing
The Problem: Materials with low density, high strength, and high stiffness are desirable for many applications. Cellular materials like syntactic foams possess high compressive strength and stiffness at an extremely low density. 3D-printable foams would assist in creating a novel class of 3D-printed hybrid materials and structures with unprecedented...

New Bending Actuators for Soft Robots
The Problem: Soft and continuum robots show great promise for a variety of applications. However, current actuation strategies present challenges in robotic control and performance. Tendon actuation is hampered by friction and fluidic actuation requires bulky actuation systems that are imprecise and difficult to control. In addition, these strategies... (read more) -
Improved Filtration Efficiencies in Nonwoven Materials via Novel Hydrostatic Charging Methods
The Problem:Electrostatic charging of fibrous materials, like filter media, can increase the filtration efficiency of these materials. Corona charging is one method of charging the fabrics, while hydrocharging methods like triboelectrification can achieve a higher filtration efficiency. However, this method is more time consuming and tedious because... (read more) -
Smart Joint: An Integrated System for Monitoring the Integrity of Adhesive Joints
The Problem: The formation and integrity of adhesive structural joints between similar or dissimilar materials can be unpredictable because of potential variations in the surfaces being joined or in the approach used in joining them. Thus, there is an ongoing need for methods and systems to monitor the structural health of adhesive joints and for determining... (read more) -
Fast Separation of Rare Earth Elements Using Gas Thermochromatography
The Problem:The rare earth element market is heavily controlled by China, but to reduce reliance on China for these materials, more efficient extraction techniques are needed. However, conventional solution-phase techniques used to separate rare earth elements are generally slow and costly and require extensive sample preparation.The Solution:Researchers... (read more) -
Manufacture of Carbon Fiber Intermediate Products In-Line with Carbon Fiber Production
The Problem:Carbon fiber composite materials have expanded significantly over the past 30 years into numerous application areas. However, continued growth is limited due to high costs of the materials and the cost to produce intermediate products such as pre-impregnated tapes and compounded molding pellets that are needed for downstream application...
