The electric tattoo is even better than an Apple watch for spotting heart trouble early
- The patch has two wired sensors which measure two functions of the heart
Scientists in the U.S. have developed an electronic stick-on patch that can monitor the heart and detect signs of illness, such as irregular rhythm, before they cause serious problems.
The ultra-thin patch — called an ‘e-tattoo’ because it looks like a temporary tattoo sticker — has two wired sensors incorporated into its design which continuously measure two functions of the heart.
It can carry out both an electrocardiogram (ECG) to check the heart’s rhythm and electrical activity, and a seismocardiogram (SCG), which measures the vibrations generated by heart valves as they open and close when the heart beats.
The e-tattoo, which is roughly the size of a credit card, is the first mobile device to be able to carry out both these tests, allowing the electrical and mechanical functions of the heart to be monitored at the same time.
The developers, from the University of Texas at Austin, say it could be a major boost in tackling heart disease by detecting problems early, when they are much easier to treat.

In the UK, for example, it’s estimated that there are over 300,000 people with undetected atrial fibrillation (AF), a common heart rhythm disorder which raises the risk of stroke.
The e-tattoo could also be offered to people with symptoms of heart disease, such as nausea, heartburn and sweating.
Home remedies
Traditional treatments that really work. This week: Olive oil massage for arthritis pain
A 2012 study in the Journal of Clinical Rheumatology compared olive oil massage to the use of Piroxicam gel (an anti-inflammatory painkiller) in 58 people with osteoarthritis of the knee — and found a threefold greater reduction in pain in the olive oil group after four weeks.
Ali Mobasheri, a professor of musculoskeletal physiology at the University of Surrey, explains: ‘Olive oil contains anti-inflammatory ingredients that can penetrate the skin. This, plus the action of massage, can help improve circulation and affect the pressure nerves involved with pain.’
‘If we can have continuous, mobile monitoring at home, then we can do early diagnosis and treatment, and if that can be done, 80 per cent of heart disease can be prevented,’ says Nanshu Lu, a professor in the department of aerospace and engineering mechanics, where the device has been developed.
Currently, patients with suspected heart disease are monitored in hospital or are given cumbersome devices to use at home. The e-tattoo is less intrusive and more comfortable to wear.
And while smart watches can carry out an ECG, to date, they are not able to perform an SCG, which is normally checked using a stethoscope. When these two tests are combined, they provide vital information about how efficiently blood is pumping through the heart.
The data collected by the e-tattoo is sent via Bluetooth to an app, which can be viewed by the patient’s medical team.
The e-tattoo itself is attached to the chest like a medical dressing — and it is powered by a very small battery, which lasts for around 40 hours and can be easily changed by the user.
So far, researchers have tested the patch on five healthy men in their 20s and found it had a low error rate compared with other available monitoring options, reported the journal Advanced Electronic Materials in April. Larger studies are planned.
‘Our work manifests that chest e-tattoos have the potential to eventually become a medical-grade, long-term, ambulatory cardiovascular monitoring tool,’ the researchers said.

Chris Gale, a professor in cardiovascular medicine at the University of Leeds, said: ‘The technology for continuous monitoring of a person’s heartbeat is advancing at an amazing pace.
Rude health
Mathematicians at the University of Sussex have come up with the formula for men reaching sexual climax.
Using data from the male arousal cycle in 10,000 men, they found too much psychological arousal early in the process can inhibit the chance of climax, so ‘don’t overthink it’, the researchers said.
‘Small, non-intrusive wearables such as this, that allow the monitoring of heartbeats for long periods of time, will allow the detection and diagnosis of many more arrhythmias, as well as offering reassurance to patients who may have symptoms yet have normal heart beats.’
n Measuring a stress hormone in hair can reveal if you’re at risk of heart disease, according to a study presented at the European Congress on Obesity last month.
This found that people with higher cortisol levels in their hair were twice as likely to have a stroke or heart attack in the following seven years as those with lower levels.
This rose to over three times as likely in those aged 57 years or younger, according to the study.
It’s thought that stress hormones, which are readily detectable in hair because cortisol becomes incorporated into hair as it grows, affect the body’s metabolism and fat distribution and this could play a role in heart disease.
Tyres and brake pads could make asthma worse
Could living next to a busy road junction be bad for asthma?
UK researchers are investigating the link between ‘non-exhaust’ air pollution — caused by tiny particles from wear on vehicle tyres and brake pads — and asthma symptoms.
The 48 patients taking part in the trial will be exposed to three different environments: a high-speed road (which has high levels of tyre wear emissions), a busy road junction (with high levels of brake pad emissions), and a location away from traffic.
Researchers at Queen Mary University of London will compare breathing test results from each location to see what impact these environments have on the participants’ asthma symptoms.
Caffeine may stop delirium after an op
Caffeine is being tested as a way to stop delirium after surgery. In a new trial at the University of Michigan, around 250 patients will be given 30-minute infusions of caffeine or a placebo after their operation.
Doctors will then compare the rates of post-operative delirium one and two days later. Delirium following surgery is increasingly common with age.
Symptoms include agitation and mood swings, hallucinations, slurred speech and difficulty in concentration. The cause is not yet known, but one theory is that the high levels of inflammation that result from surgery disrupt brain function.
It’s thought that caffeine can ‘reset the brain’s processing ability’ by speeding up communication between our brain cells.
Secrets of an A-List body
This week: Kylie Minogue’s legs
Australian singer Kylie Minogue showed off toned legs in a picture she recently posted on Instagram (below).
The 55-year-old says she keeps in shape with Pilates and treadmill training — but nothing too fast. ‘We say in my family, ‘Minogues don’t run.’ But we like to walk, so that works for me,’ she says.
WHAT TO TRY: Sit-to-stands are the perfect way to tone the entire leg and bottom.
Stand in front of a chair, facing away from it, with your feet shoulder-width apart. Slowly sit down, take a breath, then push back up through your feet to stand without using your hands.
Try the same move on one leg. Repeat 15 times to activate the legs, then take a short but brisk walk to raise your heart rate and improve your cardiovascular health.
