Diaphragm excursion and thickness in patients with chronic low back pain with and without lumbar instability

Scientific Reports
Diaphragm is crucial for respiration and plays a significant role in trunk stabilization, particularly during postural tasks. Several studies have focused primarily on trunk muscles in lumbar instability (LI) patients.

Soft Ionic and Electronic Triboelectric Nanogenerators: Toward Attachable and Implantable Biomedical Applications

Advanced Materials, EarlyView.
This review provides an overview of triboelectric nanogenerator (TENG)–based biomedical applications by classifying studies into electronic and ionic systems across attachable and implantable platforms. It summarizes key material choices, device structures, and working mechanisms that characterize current TENG‐based research, and outlines six future ...

Fiber Bragg Grating Pressure Sensor Integrated with Epoxy Diaphragm

Sensors, 2021
A fiber Bragg grating (FBG) sensor integrated with an epoxy diaphragm was developed for the measurement of pressure and water level. The bending strain of a circular diaphragm induced by uniform pressure was transferred to the FBG sensor. The response of

Development of low frequency, insulating thick diaphragms for power MEMS applications [PDF]

Sensors and Actuators A: Physical, 2013
Major challenges of micro thermal machines are the thermal insulation and mechanical tolerance in the case of sliding piston. Switching from piston to membrane in microengines can alleviate the latest and lead to planar architectures. However, the thermal isolation would call for very thick structures which are associated to too high resonant ...

Study of a Novel Bi‐Layered Thermoplastic Polyurethane Patch for Congenital Diaphragmatic Hernia

Advanced Materials Interfaces, EarlyView.
Large congenital diaphragmatic hernia remains a challenge due to the poor compatibility of current prostheses. To tackle this problem, a bilayer thermoplastic polyurethane patch with tunable mechanical properties is engineered, whose fibrous side supports rapid fibroblast and myoblast colonization, while the smooth film limits adhesions.

Diaphragm thickness and inspiratory strength in patients with Duchenne muscular dystrophy [PDF]

Thorax, 1997
There is little information on the morphometric characteristics of the diaphragm in patients with Duchenne muscular dystrophy.The thickness of the diaphragm was measured at the zone of apposition using B mode ultrasonography in 10 boys with Duchenne muscular dystrophy of mean (SD) age 10.3 (1.3) years and 12 normal controls of mean (SD) age 11.3 (2.0 ...
