Tunable Dynamic Walking via Soft Twisted Beam Vibration
Background Actuation and transmission through soft robotic systems has been studied extensively in recent years. Soft actuators, unlike traditional rigid-body robotic systems, can be deformed to subsequently alter body shapes and drive robots by stimulating or deforming soft materials. While many soft actuators have been developed to drive soft robots...

Membraneless Method for Electricity Generation from Salinity Gradients
Background Blue energy, which is the Gibbs energy that results from mixing seawater and river water, is a promising source of clean energy. Pressure-retarded osmosis (PRO) and reverse electrodialysis (RED) are currently the most successful methods for extracting such energy. However, their performance is limited by challenging issues associated with...

Pinched Tubes for Reconfigurable Robots
­Background When a soft tube is pinched, its stiffness is lowered at the pinching location, making it possible to buckle the tube at the pinch location. This phenomenon can be stimulated through the use of mechanical interference and vacuum, tendon-based pulling forces, or by pushing out a hinge from the inside. Once pinched, a hinge is formed...

Soft, Curved, Reconfigurable Buckling Beams for Underwater and Terrestrial Autonomous Vehicles
­Background Tape springs (or tape measures) exhibit nonlinear stiffness and asymmetric behavior when bent in one direction compared to the opposite direction. This behavior can be utilized, tuned and actively reconfigured to achieve locomotion on land and in fluids. Even in the presence of symmetric flapping, a swimming gait similar to “breaststroke”...

Fish-Inspired Robot with Pectoral Fins
Background Unchecked growth of algae and unwanted plants in bodies of water can result in undesirable changes that affect ecological stability, recreational value, and human health. Surface overgrowth of aquatic plants and algae restrict swimming, fishing, and boating, while depleting oxygen available for fish and other plant life. Excess levels of...

Memristor Random Number Generator
True random number generators (TRNGs) are used in cryptography and cyber security, and are increasingly important in an interconnected world at risk from cyber threats. Hardware random number generators use physical variables, such as thermal noise or the photoelectric effect, as sources of randomness in number generation. However, they suffer from...

Neuromorphic Computing Memristive Device
Resistance switching devices, also known as memristive devices, represent the next generation in computing. With a typical metal/insulator/metal structure, memristors change resistance based on past current flow and retain this new resistance even when turned off. This allows memristors to store data without needing constant power like in traditional...
