An Adaptive Mechatronic Exoskeleton for Force-Controlled Finger Rehabilitation

Frontiers in Robotics and AI, 2021
This paper presents a novel mechatronic exoskeleton architecture for finger rehabilitation. The system consists of an underactuated kinematic structure that enables the exoskeleton to act as an adaptive finger stimulator.

The variability of exoskeleton elements in polyplacocystis ambigua (protista, centrohelida) [PDF]

, 2008
Article dealt with the investigation of variability of the scales of periplast in Polyplacocystis ambigua (Penard, 1904). New quantative character of periplast scale (wide of rim) was introduced. Renewed diagnosis of P.

Structure Formation in Butterfly Scales: Interplay of Genetic Control, Mechanical Instabilities, and Dynamic Material Properties

Advanced Functional Materials, EarlyView.
Butterfly wing scales are intricate cuticular functional nanosctructures. This perspective suggests that spatially varying material properties, cytoskeletal constraints, and growth‐driven mechanical instabilities shape the resulting nanoscale architectures created from single cells.

Exoskeletons for all: The interplay between exoskeletons, inclusion, gender, and intersectionality [PDF]

Paladyn, Journal of Behavioral Robotics, 2020
AbstractIn this article, we investigate the relation between gender and exoskeleton development through the lens of intersectionality theory. Exoskeleton users come in a wide variety of shapes, sizes, and genders. However, it is often the case that wearable robot engineers do not develop such devices primarily on the premise that the product should fit

Chemically Doped Conductive Polymers for Wearable Health Monitoring

Advanced Materials Technologies, EarlyView.
Among conductive polymers, poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), polyaniline (PANI), and polypyrrole (PPy) are the most studied and applied. Chemical doping significantly boosts intrinsic conductivity and mechanical robustness.
