Design and Modeling of a Parallel-Pipe-Crawling Pneumatic Soft Robot

open access: yesIEEE Access, 2019
Soft robots have unique advantages over traditional rigid robots and have broad application prospects in many fields, such as pipe inspections. Several of the reported pipe-crawling soft robots have long actuation periods and small locomotion speeds ...

An earthworm-inspired soft crawling robot controlled by friction [PDF]

open access: yesIEEE International Conference on Robotics and Biomimetics, 2017
We present the design, fabrication, modeling and feedback control of an earthworm-inspired soft robot that crawls on flat surfaces by actively changing the frictional forces acting on its body.

Anomalous Stiffening of a Conjugated Polymer During Electrochemical Oxidation

open access: yesAdvanced Functional Materials, EarlyView.
The electromechanical response of a thienothiophene‐based conjugated polymer with triethylene glycol side chains is investigated. Electrochemical nanoindentation and atomic force microscopy reveal a modest and reversible increase in elastic modulus at room temperature upon electrochemical oxidation.

Knowledge of mothers regarding infant’s developmental milestones in four domains (gross motor, fine motor, language and personal and social) – A cross sectional study

open access: yesJournal of Family Medicine and Primary Care
Background: In India, children with neurodevelopmental disabilities are being referred late. One of the possible reasons could be lack of mothers’ knowledge regarding developmental milestones.

How crawling and manual object exploration are related to the mental rotation abilities of 9-month-old infants

open access: yesFrontiers in Psychology, 2013
The present experiment examined whether the mental rotation ability of 9-month-old infants was related to their abilities to crawl and manually explore objects. Forty-eight 9-month-old infants were tested; half of them had been crawling for an average of

Colloidal Crack Sintering Lithography for Light‐Induced Patterning of Particle Assemblies

open access: yesAdvanced Functional Materials, EarlyView.
Colloidal crack sintering lithography (CCSL) is a microfabrication technique that uses light‐induced photothermal heating to trigger sintering and controlled cracking in polymer colloidal assemblies. Local structural changes generate microchannels and patterns, enabling direct writing of diverse topographic motifs.

Il futuro regime dei tassi di cambio.

open access: yesMoneta e Credito, 2014
When the Committee of Twenty decided to rename the exchange-rate regime rather than reform it, some two weeks after the system had collapsed, it immediately became clear that the ambitious attempt to write a new monetary constitution for the world had ...

Adaptive 4D‐Printed Vascular Stents With Low‐Temperature‐Activated and Intelligent Deployment

open access: yesAdvanced Functional Materials, EarlyView.
Microarchitected coronary artery stents were fabricated using a polycaprolactone (PCL)‐based shape memory polymer (SMP) composite via projection micro‐stereolithography (PµSL) 4D printing. By incorporating diethyl phthalate (DEP) as a plasticizer, the thermal transition temperature (Ttran) was modulated to about 37°C, enabling rapid and autonomous ...
