On the Biomimetic Design of the Berkeley Lower Extremity Exoskeleton (BLEEX)

Proceedings of the 2005 IEEE International Conference on Robotics and Automation, 2006
Many places in the world are too rugged or enclosed for vehicles to access. Even today, material transport to such areas is limited to manual labor and beasts of burden. Modern advancements in wearable robotics may make those methods obsolete. Lower extremity exoskeletons seek to supplement the intelligence and sensory systems of a human with the ...

Extreme Biomimetics: formation of zirconium dioxide nanophase using chitinous scaffolds under hydrothermal conditions†

Journal of Materials Chemistry B, 2013
Chitinous scaffolds isolated from the skeleton of marine sponge Aplysina cauliformis were used as a template for the in vitro formation of zirconium dioxide nanophase from ammonium zirconium(iv) carbonate (AZC) under extreme conditions (150 °C). These novel zirconia-chitin based composites were prepared for the first time using hydrothermal synthesis ...

Preparation of monolithic silica–chitin composite under extreme biomimetic conditions

International Journal of Biological Macromolecules, 2015
Chitin is a widespread renewable biopolymer that is extensively distributed in the natural world. The high thermal stability of chitin provides an opportunity to develop novel inorganic-organic composites under hydrothermal synthesis conditions in vitro.

Biomimetic design and biomechanical simulation of a 15-DOF lower extremity exoskeleton

2013 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2013
Lower extremity exoskeletons can improve human strength and endurance with a pair of wearable robotic legs that support a payload. This paper summarizes the biomimetic design and biomechanical analysis of a novel 15-DOF (degree of freedom) lower extremity exoskeleton.

An extreme biomimetic approach: hydrothermal synthesis of β-chitin/ZnO nanostructured composites

Journal of Materials Chemistry B, 2013
β-Chitinous scaffolds isolated from the skeleton of marine cephalopod Sepia officinalis were used as a template for the in vitro formation of ZnO under conditions (70 °C) which are extreme for biological materials. Novel β-chitin/ZnO film-like composites were prepared for the first time by hydrothermal synthesis, and were thoroughly characterized using

Extreme biomimetic approach for developing novel chitin-GeO2 nanocomposites with photoluminescent properties

Nano Research, 2015
This work presents an extreme biomimetics route for the creation of nanostructured biocomposites utilizing a chitinous template of poriferan origin. The specific thermal stability of the nanostructured chitinous template allowed for the formation under hydrothermal conditions of a novel germanium oxide-chitin composite with a defined nanoscale ...

Biomimetic titanium dioxide film with structural color and extremely stable hydrophilicity

Applied Physics Letters, 2004
We biomimeticly fabricated titanium dioxide films with three-dimensionally ordered structure. These films exhibit structural color, photocatalysis, and photoinduced superhydrophilicity. In addition, this biomimetic approach solves the problem of the stability of the superhydrophilicity of titanium dioxide.

Learning-based Biomimetic Strategies for Developing Control Schemes for Lower Extremity Rehabilitation Robotic Devices

2023
Lower limb disabilities caused by factors such as amputation, neuromuscular impairment, and traumatic injury can significantly impact mobility and quality of life. To restore impaired functionality, individuals may use assistive devices such as prostheses, orthoses, or exoskeletons.

Fiber Sedimentation and Layer-By-Layer Assembly Strategy for Designing Biomimetic Quasi-Ordered Mullite Fiber Aerogels as Extreme Conditions Thermal Insulators

ACS Applied Materials & Interfaces, 2023
Ceramic fiber aerogels are attractive thermal insulating materials. In a thermomechanical coupling environment, however, they often show limited mechanical strength and considerably increased heat transfer which can lead to thermal runaway. In this paper, inspired by bird's nest and nacre, we demonstrate a sample strategy combining fiber sedimentation ...
