Cervical spine musculotendon lengths when reading a tablet in three seated positions
(Human Kinetics, 2021-04-01)A popular posture for using wireless technology is reclined sitting, with the trunk rotated posteriorly to the hips. This position decreases the head’s gravitational moment; however, the head angle relative to the trunk ... -
Detection of dissolved CO2 gas using an open-circuit resonator
(Wichita State University, 2021-04-02)Exposure to higher than normal levels of carbon dioxide (CO2) gas increases its concentration in the blood, which can impair cognitive function and cause adverse physical effects. This is especially a concern in aerospace ... -
S.E.L.E.N.E: System Engineered for Lunar Environment, Navigation, and Exploration
(Wichita State University, 2021-04-02)Augmented Reality (AR) display technologies utilize computer-generated virtualized content to enhance the observer's perception of the physical environment. This NASA SUITS (Spacesuit User Interface Technologies for Students) ... -
The long-term effects of daily smartphone usage on cervical spine kinematics
(Wichita State University, 2021-04-02)INTRODUCTION: It is evident that in today's technologically run world, the majority of individuals own and interact with a smartphone throughout their daily lives. This constant interaction poses significant risks to a ... -
Brain-computer interface to control a 6 DOF robotic arm
(Wichita State University, 2021-04-02)In this study, a brain-computer interface (BCI) system is developed to control a six degrees of freedom robot arm. Such interface systems have a potential application in space missions for astronauts to have supplemental ... -
Enhancing the performance of elastomer actuators through the approach of distributed electrode array with fractal interconnects architecture
(Wichita State University, 2021-04-02)Dielectric elastomer actuators are flexible and stretchable transducers which are known to achieve large displacements at high speeds and require low power for operation with applications in microrobotics, portable ... -
Improving fluid retention properties of 316L stainless steel using nanosecond pulsed laser surface texturing
(Laser Institute of America, 2020-11)stainless steel has been used as a successful biomaterial for decades. In this study, a pulsed nanosecond laser was used to create patterned surfaces of stainless steel coupons to study the effect of patterning on fluid ... -
Investigating the effect of photoinitiator concentration and curing time on soybean - Polyethylene glycol resins
(Society of Plastics Engineers, 2020)Bioprinting, a subset of additive manufacturing, utilizes bioinks, which is a combination of biomaterials and live cells, to produce functional tissue. Soybean oil is a plant polymer with promising biomaterial properties ... -
Development of flexible ion-selective electrodes for saliva sodium detection
(MDPI, 2021-03)Saliva can be used for health monitoring with non-invasive wearable systems. Such devices, including electrochemical sensors, may provide a safe, fast, and cost-efficient way of detecting target ions. Although salivary ... -
All-in-one, wireless, fully flexible sodium sensor system with integrated Au/CNT/Au nanocomposites
(Elsevier, 2021-03-15)Advancements in functional nanomaterials and wearable electronics have demonstrated the use of solid-state ion-selective electrodes (SS-ISEs) for human health applications. Existing devices, however, still rely on separate ... -
A comparison of classification techniques to predict brain-computer interfaces accuracy using classifier-based latency estimation
(MDPI AG, 2020-10-14)P300-based Brain-Computer Interface (BCI) performance is vulnerable to latency jitter. To investigate the role of latency jitter on BCI system performance, we proposed the classifier-based latency estimation (CBLE) method. ... -
Shoulder kinematics assessment towards exoskeleton development
(MDPI AG, 2020-08-11)Neuromuscular and sensorimotor degeneration caused by stroke or any other disease significantly reduce the physical, cognitive, and social well-being across the life span. Mostly, therapeutic interventions are employed in ... -
Investigating TiO2–HA–PCL hybrid coating as an efficient corrosion resistant barrier of ZM21 Mg alloy

A mattress contact model for a musculoskeletal simulation of human rolling
(Wichita State University, 2020-07)Limited mobility affects a lot of people, including those who have recently had surgery or major trauma, the geriatric population, and people with disabilities. Many people with limited mobility cannot reposition themselves ... -
The development of heparan sulfate within the glycocalyx
(Wichita State University, 2020-07)A key to protecting vessel health occurs at the interface between circulating blood and endothelial cells. Strategically located at this interface is the endothelial glycocalyx, the first “line of protection” for blood ... -
Design and evaluation of a GUI for signal and data analysis of mobile functional near-infrared spectroscopy systems
(Wichita State University, 2020-07)Functional near-infrared spectroscopy (fNIRS) is an emerging neuro-imaging modality that can indicate cortical functionality with good temporal resolution (0.5-1 sec). Unlike fMRI, up to now, there is no standard method ... -
Photocurable polymers for 3d printing
