A team of engineers from the University of Massachusetts Amherst set themselves the task instrumenting cardiac tissue as it is grown outside the body to study heart disease. Artists impression over photo: “Cardiac tissue is very special,” said Jun Yao of UMass Amherst’s college of engineering. “It has a mechanical activity – contractions and relaxations that pump blood through our ...

Stretchy PCBs in smart cardiac monitor, and more
An intelligent patch for cardiac monitoring is amongst research projects built on flexible and stretchable PCBs from Würth Elektronik. There are two cardiac monitors, a mini version with three electrodes for short-term monitoring, and one with six electrodes for longer periods. “A completely new approach to integration was developed in this work,” according to Wurth. “It was based on a stretchable ...
Machine learning finds heart faults
Russian and US scientists have used machine learning to find ‘atrial fibrillation (AF) drivers’ – small patches of faulty heart muscle that can cause cardiac arrhythmia. The team tested their approach on 11 donated human hearts and located AF drivers with an accuracy of up to 81%. Multi-electrode mapping (MEM) is a technique that can be applied during an operation, ...
Stretchy heart monitor tattoo measures electrical and mechanical body signals
Electrocardiograph and seismocardiograph readings can be taken simultaneously by an e-tattoo, according to the University of Texas at Austin – seismocardiography (SCG) is a measure of chest vibrations associated with heartbeats. “We can get much greater insight into heart health by the synchronous collection of data from both sources,” said Austin engineer Nanshu Lu. The active part is a serpentine mesh ...
Phone app and cloud-based AI could identify heart disease from the home
Artificial intelligence can recognise congestive heart failure non-invasively via by a cloud-connected phone, briging diagnosis into the home, according to a research team from Nanyang Technological University and Tan Tock Seng Hospital, both of Singapore. One in five people worldwide, according to Nanyang, run the risk of developing congestive heart failure – and this increases with age. There is no cure, and ...
MWC: iPhone gets health data over Bluetooth Low Energy
Cambridge Consultants will demonstrate Bluetooth low energy (BLE) iPhone 4S applications at Mobile World Congress. The firm worked with Cambridge-based Bluetooth chip supplier CSR on tools and example device software that assists developers wishing to create apps for Apple’s iPhones and Macs. “One key target group for this being the growing mobile health market,” said CCL. “BLE enables ultra-low power ...
Ed Finds He’s Not Lawyered Up
‘Top managers are wanting to leave,’ Ed confides to his diary, ‘they tell me they don’t like the way I’m running the company – too much cost-cutting, too much focus on the short-term, too little investment etc etc. It does no good to tell them we have to pay the interest on the massive debt imposed on us by our ...
Electronic stethoscope aids heart valve diagnosis
Technology from the University of London could help doctors diagnose heart disease. "The system is designed to make it easy for doctors who normally carry around a stethoscope to record the sounds that...
IMEC puts heart beat on Android phones
Healthcare costs could be cut by an app for android phones that stores and displays electrocardiograms sensed over a wireless body area network (BAN). Hardware and software have come from consortium of: Belgian Lab IMEC, its Dutch subsidiary Holst Centre, and embedded software firm TASS. “The innovation is a low-power interface that transmits signals from a wireless ECG sensor system ...
Imperial heart implant pulses RF piezo oscillator
Imperial College is developing an implantable passive blood pressure monitor based around a SAW (surface acoustic wave) oscillator.
