It is small and easy to use so that mother’s-to-be can keep a regular check on their baby’s heart beat without having to go into hospital and be attached to a machine. No other technology allows them to do this.
It took 15 years of pioneering work and enterprise, with funding from Action Medical Research and Venture Capital, to develop the fetal heart monitor. Researchers believe the device has the potential to benefit 70,000 at risk babies a year in the UK alone.
Statistics show that as many as 10 babies a day are stillborn in the UK and 10 per cent of all pregnancies each year are high risk. The monitor lets doctors read signals produced naturally by the unborn baby’s heart. They can then intervene if necessary and potentially save their lives.
The fetal monitor is the result of years of collaborative work between engineers and doctors at the University. The original research was carried out by Dr John Crowe and Dr Barrie Hayes-Gill in the School of Electrical and Electronic Engineering (EEE) and Professor David James and Dr Margaret Ramsay in the School of Human Development. In 2005 the technology was spun out to create Monica Healthcare Ltd. Led by both Dr Hayes-Gill and two ex PhD researchers from EEE, Dr Carl Barratt and Jean Francois Pieri, the company has gone on to develop the monitor even further.
This highly sensitive device, which is able to detect 0.00000001 volts, has now been reduced to the size of a mobile phone. It can compute real time fetal readings and the resulting data can be transmitted by wireless technology to the nearest PC or hand held computer. The device has now passed all EU regulatory safety standards and is currently undergoing clinical trials.
Dr Barrie Hayes-Gill expects the device to go on sale in October this year. “To date we have successfully completed over 33 per cent of the clinical trial. We expect to complete clinical trials in July 2007. This represents a tremendous achievement to turn a research device into a medically approved product in only two years — an experience which will place us in good stead for future medical products that we have on our horizon.”
Currently hospital based ultrasound is used to record babies’ heart rates during pregnancy. While this technique has proven benefits, it needs to be administered by trained professionals and it is not suitable for routine, continuous, long-term monitoring. Dr Barrie Hayes-Gill and Dr John Crowe at The University of Nottingham recognised the need for a new technology that would fill these gaps.
One of the biggest obstacles in developing the fetal monitor was separating the baby’s heart beat from the mother’s signal. The team has successfully created a state-of-the-art device which can gauge both heart rates as well as fetal position. This unique home monitoring device could lead to a new approach in the management of pregnancy.
Dr Margaret Ramsay says it will play a key role in monitoring high-risk pregnancies. “For all these fetuses, the more we can monitor them, the greater the chance of us detecting that they are running into difficulties before it is too late to help them. This may involve urgent delivery of the fetus.”
The device will be especially helpful in monitoring fetuses whose mothers have medical conditions like diabetes, autoimmune conditions such as systemic lupus erythematosus and Sjogren’s syndrome and obstetric cholestasis. It will also be useful in monitoring fetuses identified as growing poorly or where it is suspected that the placenta is unhealthy and hence the fetus may become compromised due to lack of oxygen.”
In England during 2004 and 2005 17 per cent of inpatient cases for women in NHS hospitals were due to complications of pregnancy or childbirth. By helping to detect potential problems with unborn babies early and monitoring expectant mothers in their own homes it is hoped the device could relieve the pressure on in-patient stays and reduce hospital costs. As well as spotting potential complications the new monitor can be used to provide reassurance and mother-baby bonding.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
