A Predictive Design Framework for a Soft Robotic Ventricle using Contractile Actuators
Jeongmin Kim, Qiong Wang, Liuyang Cheng +4
The natural cardiac cycle is divided into the systole and diastole phases which encompass four distinct stages: isovolumetric contraction and ejection during systole, followed by i…
Actuation mechanisms in twisted and coiled polymer actuators using finite element model
Gurmeet Singh, Qiong Wang, Samuel Tsai +3
Twisted and coiled polymer actuators (TCPAs) offer the advantages of large stroke and large specific work as compared to other actuators. There have been extensive experimental inv…
How do imperfections cause asymmetry in elastic snap-through?
Andrea Giudici, Weicheng Huang, Qiong Wang +4
A symmetrically-buckled arch whose boundaries are clamped at an angle has two stable equilibria: an inverted and a natural state. When the distance between the clamps is increased…
The mechanics and physics of twisted and coiled polymer actuators
Qiong Wang, Anan Ghrayeb, SeongHyeon Kim +2
Twisted and coiled polymer actuators (TCPAs) generate large contractile mechanical work mimicking natural muscles, which makes them suitable for robotics and health-assistive devic…
Transient amplification of broken symmetry in elastic snap-through
Qiong Wang, Andrea Giudici, Weicheng Huang +4
A snap-through bifurcation occurs when a bistable structure loses one of its stable states and moves rapidly to the remaining state. For example, a buckled arch with symmetrically…
