Disclosed herein are spinal cord models including a cell scaffold including methacrylated hyaluronic acid (HAMA) and dopamine-modified hyaluronic acid (HA-Cat), and a spinal cord spheroid or organoid or a fragment thereof cultured on the cell scaffold. Said spinal cord spheroids or organoids or fragments thereof can be co-cultured with blood vessel spheroid organoids to form blood-spinal cord barrier models. Also disclosed herein are methods of making and using said models.

Viscoelastic hydrogel regulation of organoid patterning and vascularization

The present invention includes scalable and cost-effective auxetic foam sensors (AFS) created through conformably coating a thin conductive nanomaterial-sensing layer on a porous substrate having a negative Poisson's ratio. In general, the auxetic foam sensors possess multimodal sensing capability, such as large deformation sensing, small pressure sensing, shear/torsion sensing and vibration sensing and excellent robustness in humidity environment.

Negative Poisson ratio piezoresistive sensor and method of manufacture

A novel material for producing auxetic foams is disclosed. The material comprises a multiphase, multicomponent polymer foam with a filler polymer having a carefully selected glass transition temperature. Novel methods for producing auxetic foams from the material are also disclosed that consistently, reliably and quickly produce auxetic polyurethane foam at about room temperature (25&#xb0; C.). This technology overcomes challenging issues in the large-scale production of auxetic PU foams, such as unfavorable heat-transmission problem and harmful organic solvents.

Material systems and methods of manufacture for auxetic foams

Negative poisson ratio piezoresistive sensor and method of manufacture

Provided herein are methods off functionalizing a carbon nanotube, functionalized carbon nanotubes, methods of forming a suspension, and methods of forming a sensor. The methods may include contacting one or more carbon nanotubes with a dienophile in the presence of a supercritical fluid to form one or more functionalized carbon nanotubes. The one or more functionalized carbon nanotubes may have a degree of functionalization of about 1% to about 5%.

Functionalized carbon nanotubes and methods

Thermally stable piezoelectric polymer foams (ferroelectrets) with high piezoelectric activity for sensing and actuation. The invention further includes a method of fabricating such foams in an environmentally friendly manner.

Method of manufacture for polymer foam-based piezoelectric material

A process is disclosed for removing impurities from a carbon nanotube structure and then orienting the nanotubes within the structure. The process may use environmentally benign materials and minimize damage to the carbon nanotubes. The process may provide a cost-effective way to manufacture nanomaterials based macroscopic parts and components, whose properties approach to those of the individual nanoparticles.

Polymer foam-based piezoelectric materials and method of manufacture

A prosthetic sock for a patient to wear over a residual limb is provided. The prosthetic sock includes an inner layer configured to fit over at least a portion of the residual limb of the patient. A foam layer is disposed on an outer surface of the inner layer. The foam layer compensates for changes in shape or volume of the residual limb within the prosthetic sock by changing shape in a manner effective to maintain a secure fit between the residual limb and a prosthetic socket of a prosthetic limb.

Prosthetic socket apparatus and systems

Fire retardant materials are provided that contain carbon nanotubes and particles capable of endothermically reacting when exposed to elevated temperatures. The carbon nanotubes may be a buckypaper. Methods also are provided for making a fire retardant material and for improving the fire retardation capabilities of a material.
