Q&A: Wearable Motion Sensors Could Save Unborn Babies

  • Magazine Article
  • TBMG-35275
Published 2019-10-01 by Tech Briefs Media Group in United States

Negar Tavossolian is Associate Professor of Electrical and Computer Engineering at Stevens Institute of Technology, Hoboken, NJ. She led a project to develop a lightweight, non-invasive sensor to monitor fetal heart rate and motion that could sense abnormalities warning of possible stillbirths.

Monitor Babies in the NICU Without Wires

An interdisciplinary Northwestern University team has developed a pair of soft, flexible wireless sensors that replace the tangle of wire-based sensors that currently monitor babies in hospitals’ neonatal intensive care units (NICU) and pose a barrier to parent-baby cuddling and physical bonding. The lead researcher was John A. Rogers, a bioelectronics pioneer, who led the technology development. The team recently completed a series of first human studies on premature babies at Prentice Women’s Hospital and Ann & Robert H. Lurie Children’s Hospital of Chicago. The researchers concluded that the wireless sensors provided data as precise and accurate as that from traditional monitoring systems. The wireless patches also are gentler on a newborn’s fragile skin and allow for more skin-to-skin contact with the parent. Existing sensors must be attached with adhesives that can scar and blister premature newborns’ skin. The study, involved materials scientists, engineers, dermatologists, and pediatricians. It includes initial data from more than 20 babies who wore the wireless sensors alongside traditional monitoring systems, so the researchers could do a side-by-side, quantitative comparison. Since then, the team has conducted successful tests with more than 70 babies in the NICU.

Patch Improves Care for NICU Babies

When a baby is placed into a neonatal intensive care unit (NICU), its vitals are continuously recorded through electrodes placed on the skin with wires attached to monitoring platforms. Researchers are working to replace the wires with a patch that would allow parents to hold their little one while it's being monitored.

Handheld Probe Images Photoreceptors in Children

Duke University researchers have developed a handheld probe that can image individual photoreceptors in the eyes of infants. The technology, based on adaptive optics, will make it easier for physicians and scientists to observe these cells to diagnosis eye diseases and make early detection of brain-related diseases and trauma.

Nonprofit Pushes Design Limits to Develop Life-Saving Technology for Underprivileged Communities

Nearly four million infants in developing countries die each year within a month of birth due to complications of prematurity, low birth weight, and infection. Design that Matters (DtM), a nonprofit organization, is committed to helping prevent these deaths by providing the medical devices needed to give at-risk newborns a warm and clean environment to help them grow strong.

New Patch Aims to Turn Energy-Storing Fats into Energy-Burning Fats

Published 2018-02-01 by Tech Briefs Media Group in United States

A new system combines a new way to deliver drugs, via a micro-needle patch, with drugs that are known to turn energy-storing white fat into energy-burning brown fat. This innovative approach developed by scientists from Nanyang Technological University, Singapore (NTU Singapore), reduced weight gain in mice on a high fat diet and their fat mass by more than 30 percent over four weeks.

Device-Free Motion Tracing Using WiFi Signals

  • Magazine Article
  • TBMG-27979
Published 2017-12-01 by Tech Briefs Media Group in United States

Fine-grained human motion tracing — the ability to trace the trajectory of a moving human hand or leg, or even the whole body — is a general capability that is useful in a wide variety of applications. It can be used for gesture recognition and virtual touch-screens (e.g. Kinect-style natural user interfaces), activity recognition, monitoring of young infants and the elderly, or security applications such as intruder detection. Motivated by these applications, depth-sensing-based systems have been developed to implement motion tracing capabilities in cameras; however, these devices are limited because they have a constrained field of view (around 2 to 4 m range with a 60-degree aperture), and do not work in non-line-of-sight scenarios, preventing their use in many applications such as whole-home activity recognition, security, and elderly care.

Handheld Spectral Analyzer for Point-of-Care Diagnostics

Published 2017-12-01 by Tech Briefs Media Group in United States

A spectral transmission-reflectance-intensity (TRI) analyzer was developed that attaches to a smartphone and analyzes patient blood, urine, or saliva samples as reliably as clinic-based instruments. It is capable of performing thousands of current tests that may be adapted to the device, including an enzyme-linked immunosorbent assay (ELISA) that detects and measures a wide variety of proteins and antibodies in blood, and is commonly used for a wide range of health diagnostics tests. The system is capable of detecting the output of any test that uses a liquid that changes color, or a liquid that generates light output (such as from fluorescent dyes).
