Current surgical devices are mostly rigid and are made of stiff materials, even though their
predominant use is on soft and wet tissues. With the emergence of compliant mechanisms …

The embodiments described herein can be used in a variety of gras**, cutting, and
manipulating operations. In some embodiments, an apparatus includes a first joint member …

Origami has recently emerged as a platform for building functional engineering systems with
versatile characteristics that targeted niche applications. One widely utilized origami-based …

To overcome the constraint of conventional tilted beam-based bistable mechanism, this
paper proposes a novel type of bistable structure based on tilted-angle compound …

In the field of medical instruments, additive manufacturing allows for a drastic reduction in
the number of components while improving the functionalities of the final design. In addition …

This paper proposes the design of a wholly mechanical constant-force gripper that can
accommodate the imprecise manipulation of brittle/delicate objects by the actuation. This …

This work introduces the concept of applying binary-stiffness beams within a lattice to
achieve a mechanical neural-network (MNN) metamaterial that learns its behaviors and …

Stiffness in compliant micro mechanisms can negatively affect performance. Current
methods for stiffness reduction in micro electro mechanical systems (MEMS) consume …

Stiffness in compliant mechanisms can be dramatically altered and even eliminated entirely
by using static balancing. This requires elastic energy to be inserted before operation, which …

Background Although minimally invasive surgery (MIS) affords several advantages
compared to conventional open surgery, robotic MIS systems still have many limitations …
