Engineers have developed a new wearable, ultra-thin electronic device – e-tattoo – that could make heart monitoring easier and more accurate than existing electrocardiograph machines. Developed by engineers from the University of Texas at Austin, the graphene-based ‘e-tattoo’ can be placed on the skin to measure a variety of body responses, from electrical to biomechanical signals.

The electronic device is so lightweight and stretchable that it can be placed over the heart for extended periods without any discomfort, according to the engineer’s research, published in the Advanced Science journal. Moreover, it measures cardiac health in two ways — taking electrocardiograph and seismocardiography readings simultaneously.


Most of us are familiar with already existing technologies such as Electrocardiogram (ECG), a method that records the rates of electrical activity produced each time the heart beats and Seismocardiography (SCG), a measurement technique using chest vibrations associated with heartbeats.

Whereas, this new e-tattoo, powered remotely by a smartphone, is the first ultra-thin technology to measure both ECG and SCG.

“We can get much greater insight into heart health by the synchronous collection of data from both sources,” said Nanshu Lu, Associate Professor at the University of Texas at Austin. The ECG readings alone are not accurate enough for determining heart health but they provide additional information when combined with SCG signal recordings, said researchers.

The e-tattoo is made of a piezoelectric polymer called polyvinylidene fluoride, capable of generating its own electric charge in response to mechanical stress. Besides, it also includes 3D digital image correlation technology that is used to map chest vibrations in order to identify the best location on the chest to place the e-tattoo.

Rihanna was summoned from her seat to accept the honour, with the Prime Minister.

Singer Rihanna was honoured by Prime Minister Mia Mottley at an event which marked Barbados's new status as a republic, which was attended by Prince Charles. Addressing the pop star by her real name, the PM said: "Robyn Rihanna Fenty tomorrow morning shall have conferred upon her the order of national hero of Barbados."

Rihanna was then summoned from her seat to accept the honor, with the Prime Minister managing to rouse a laugh from the singer when she referenced her 2012 hit 'Diamonds', reports femalefirst.co.uk. She added: "On behalf of a grateful nation, but an even prouder people, we therefore present to you, the designee, for the national hero of Barbados." "And to accept on behalf of a grateful nation - you can come my dear - ambassador Robyn Rihanna Fenty, may you continue to shine like a diamond and bring honor to your nation." Rihanna, who was born in the St Michael parish of Barbados, found fame in 2005 after being spotted by a record producer and has since gone on to become one of the most successful female artists of all time with sales of over 250 million and recently reached billionaire status through her Fenty beauty brand.

The Prime Minister continued in her speech: "Commanding the imagination of the world through the pursuit of excellence, her creativity, her discipline, and above all else, her extraordinary commitment to the land of her birth. "Having satisfied that, Ambassador Robyn Rihanna Fenty has given service to Barbados which has been exemplified by visionary and pioneering leadership, extraordinary achievement and the attaining of the highest excellence to the Government of Barbados." It comes after a historic move for Barbados, which has become a republic after almost 400 years and welcomes its first president, Sandra Mason, after removing Queen Elizabeth as head of state.

By IANSlife

Have you ever faced eye redness? Or have witnessed blurry or foggy vision? Or experiencing halos around lights? Or nausea and vomiting are very common for you. You may well be suffering from Glaucoma which needs immediate attention.

Glaucoma is the second most common causes of blindness worldwide, according to a report by World Health Organisation (WHO). Typically, it occurs in people with over the age of 60 however it can occur at any age. It is also estimated that globally 79.6 million people are affected with glaucoma, half of them being Asian population. While in India, around 11.9 million people suffer vision impairment and out of which 1.2 million cases are due to Glaucoma. It is a growing concern for the population in India. Even after these high numbers, the enormous majority remains undiagnosed, and untreated. More than 90 percent of cases of Glaucoma remain undiagnosed.
