Adapted assistance and resistance training with a knee exoskeleton after stroke
(2023-08-09)
Article
Open AccessStudies on robotic interventions for gait rehabilitation after stroke require: (i) rigorous performance evidence; (ii) systematic procedures to tune the control parameters; and (iii) combination of control modes. In this ... -
Inertial sensors for gait monitoring and design of adaptive controllers for exoskeletons after stroke: a feasibility study
(Frontiers Media SA, 2023-08-07)
Article
Open AccessIntroduction: Tuning the control parameters is one of the main challenges in robotic gait therapy. Control strategies that vary the control parameters based on the user’s performance are still scarce and do not exploit the ... -
Coupling capillary-driven microfluidics with lateral flow immunoassay for signal enhancement
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-08-01)
Article
Open AccessMicrofluidics has emerged as a versatile technology that is applied to enhance the performance of analytical techniques, among others. Pursuing this, we present a capillary-driven microfluidic device that improves the ... -
A state-of-the-art guide about the effects of sterilization processes on 3D-printed materials for surgical planning and medical applications: a comparative study
(2023-05-17)
Article
Open AccessSurgeons use different medical devices in the surgery, such as patient-specific anatomical models, cutting and positioning guides, or implants. These devices must be sterilized before being used in the operation room. There ... -
Analysis of ultrasonic vibration-assisted ball burnishing process on the tribological behavior of AISI 316L cylindrical specimens
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-08-12)
Article
Open AccessIn this study, we analyzed the effects of vibration assistance, combined with a ball burnishing process, in terms of topology, residual stresses, and tribological properties on 316L shafts. The burnishing variables consisted ... -
Impact of printing orientation on inter and intra-layer bonds in 3D printed thermoplastic elastomers: A study using acoustic emission and tensile tests
(Elsevier, 2023-09-22)
Article
Open AccessThe use of the Material Extrusion technique with Thermoplastic Elastomers is currently growing because of the large number of benefits of this family of materials. They are processable materials with high flexibility, which ... -
On-demand inkjet printed hydrophilic coatings for flow control in 3D-printed microfluidic devices embedded with organic electrochemical transistors
(John Wiley & sons, 2023-07)
Article
Open AccessMicrofluidic surface chemistry can enable control of capillary-driven flow without the need for bulky external instrumentation. A novel pondered nonhomogeneous coating defines regions with different wetting properties on ... -
Women, equality, and energy access: Emerging lessons for last-mile rural electrification in Brazil
(2023-08-01)
Article
Open AccessThe inaccessibility to clean and affordable energy, as well as large gender inequalities are two of the greatest challenges faced by rural areas of the Global South. However, the gender approach is still very lacking in ... -
Capillary-driven microfluidics: impacts of 3D manufacturing on bioanalytical devices
(Royal Society of Chemistry (RSC), 2023-01-01)
Article
Open AccessOver decades, decentralized diagnostics continues to move towards rapid and cost-effective testing at the point-of-care (POC). Although microfluidics has become a key enabling technology for POC testing, the need for robust ... -

A review of the efforts to develop muscle and musculoskeletal models for biomechanics in the last 50 years
(Elsevier, 2023-06-01)
Article
Restricted access - publisher's policyBoth the Hill and the Huxley muscle models had already been described by the time the International Society of Biomechanics was founded 50 years ago, but had seen little use before the 1970s due to the lack of computing. ... -
A physical-chemical study of water resources in 5 hydropower projects
(Brazilian Journals Publicações de Periódicos e Editora Ltda, 2022-11-14)
Article
Open AccessOver the last 60 years, renewable energies have substantially developed; in 2021, around 12.8% of global primary energy came from these technologies. Thus, even though renewable energies have good global acceptance present ...
