Development of a self-healing soft pneumatic actuator: a first concept.

Bioinspiration & biomimetics
Inspired by the intrinsic softness and the corresponding embodied intelligence principles, soft pneumatic actuators (SPA) have been developed, which ensure safe interaction in unstructured, unknown environments. Due to their intrinsic softness, these...

Automated electrophilic radiosynthesis of [¹⁸F]FBPA using a modified nucleophilic GE TRACERlab FXFDG.

Applied radiation and isotopes : including data, instrumentation and methods for use in agriculture, industry and medicine
We modified a commercially available synthesis module for nucleophilic [(18)F]fluorinations (TRACERlab(TM) FXFDG, GE Healthcare) to enable the reliable synthesis of 2-[(18)F]fluoro-4-borono-L-phenylalanine ([(18)F]FBPA) via direct electrophilic subst...

Quantification of loading in biomechanical testing: the influence of dissection sequence.

Journal of biomechanics
Sequential dissection is a technique used to investigate loads experienced by articular tissues. When the joint of interest is tested in an unconstrained manner, its kinematics change with each tissue removal. To address this limitation, sufficiently...

Corrugated paraffin nanocomposite films as large stroke thermal actuators and self-activating thermal interfaces.

ACS applied materials & interfaces
High performance active materials are of rapidly growing interest for applications including soft robotics, microfluidic systems, and morphing composites. In particular, paraffin wax has been used to actuate miniature pumps, solenoid valves, and comp...

Multicomponent signal unmixing from nanoheterostructures: overcoming the traditional challenges of nanoscale X-ray analysis via machine learning.

Nano letters
The chemical composition of core-shell nanoparticle clusters have been determined through principal component analysis (PCA) and independent component analysis (ICA) of an energy-dispersive X-ray (EDX) spectrum image (SI) acquired in a scanning trans...

Mechanical characterization of bone anchors used with a bone-attached, parallel robot for skull surgery.

Medical engineering & physics
Bone-attached robots and microstereotactic frames, intended for deep brain stimulation and minimally invasive cochlear implantation, typically attach to a patient's skull via bone anchors. A rigid and reliable link between such devices and the skull ...

A Biomimetic Titanium Scaffold With and Without Magnesium Filled for Adjustable Patient-Specific Elastic Modulus.

Journal of biomechanical engineering
This study focuses on determining the effective Young's modulus (stiffness) of various lattice structures for titanium scaffolds filled with magnesium and without magnesium. For a specific patient implant the success depends on adequate elastic modul...

Comprehensive Prediction of the Relative Modulus of Strut-Based Gyroid Lattice Structures Employing an ML-Based Surrogate Model.

Journal of biomedical materials research. Part B, Applied biomaterials
Due to its porous structure, tunable properties, and nearly isotropic characteristics, the Gyroid Lattice Structure (GLS) is widely utilized in orthopedic implant applications. To effectively reduce stress shielding and enhance implant longevity, it ...

A Modular, Mechanical Knee Model for the Development and Validation of Robotic Testing Methodologies.

Journal of biomechanical engineering
Six-degree-of-freedom robotic testing is used to gain insight into knee function by measuring the biomechanics of cadaveric knees. However, it can be challenging to use cadaveric knees to validate robotic testing methodologies and to compare methodol...
