Controlling knee swing initiation and ankle plantarflexion with an active prosthesis on level and inclined surfaces at variable walking speeds

Improving lower-limb prostheses is important to enhance the mobility of amputees. The purpose of this study was to introduce an impedance-based control strategy (consisting of four novel algorithms) for an active knee and ankle prosthesis and test its generalizability across multiple walking speeds, walking surfaces and users…

Experimental Procedure for Determination of the Dielectric Properties of Biological Samples in the 2-50 GHz Range

The objective of this paper was to test and evaluate an experimental procedure for providing data on the complex permittivity of different cell lines in the 2–50-GHz range at room temperature, for the purpose of future dosimetric studies. The complex permittivity measurements were performed on cells suspended in culture medium using an open-ended coaxial probe…

High-Frequency Oscillations Recorded on the Scalp of Patients with Epilepsy Using Tripolar Concentric Ring Electrodes

Electroencephalography (EEG) is a noninvasive means for recording electrical activity of the brain. We have developed tripolar concentric ring electrodes (TCREs) and have shown that TCREs provide higher signal-to-noise ratios, higher spatial resolution, and less mutual information than conventional disc electrodes. This paper describes the results of a clinical study of patients with epilepsy to determine if high-frequency oscillations (HFOs) were present in EEG recorded with TCREs.

Scope Statement

We focus on innovative solutions to healthcare needs from biomedical engineering, clinical engineering, and medical communities that bridge the engineering and clinical worlds. JTEHM's unique scope is original work at the intersection of engineering and clinical translation.

The journal’s focus is interdisciplinary collaborations among researchers, healthcare providers, and industry. We publish results and best practices from these translational efforts and serve as a community hub for researchers, clinicians, and developers who are addressing challenges in technology development, commercialization, and deployment for better global healthcare. Our ultimate goal is to improve the practice of engineering in translational medicine and to serve as a focal point for the nascent community. Our interactive content includes video, lively commentary, blogs, and other features to engage our clinical and engineering communities.
