The number of wearable technologies that use sensors as medical tools to track a person’s well-being – is on the rise. All of them – need an electric charge or a battery source to operate, but a handful of researchers are trying to take batteries out of the equation.

There has been an increasing number of wearable technologies that have health sensors as medical tools to track a person’s well-being. Many of these devices need to be charged or are battery-powered.
A handful of researchers want to take batteries out of the equation and instead, use waste body heat and convert that into useful electricity to power sensors.
“The average person is something like an 80-watt light bulb,” said Jamie Grunlan, Texas A&M University’s Linda & Ralph Schmidt ’68 Professor in Mechanical Engineering.
Grunlan and his team of researchers are working on using the waste heat the body gives off and converting that into useful electricity. The idea is to create printable, paintable thermoelectric technology that looks like ink and can coat a wearable fabric, similar to dyeing colors onto cloth. Once a person wears the fabric, devices such as health sensors can be powered.
“Our coating coats every fiber within that textile, and so what’s drawing it is simply that textile needs to just be touching the heat source or be close enough to the heat source to be feeling the heat source,” Grunlan said.
Military and sporting goods companies have applications for this type of technology because there is not a large battery pack worn on the body that could be a cause of injury if the person would fall.
“They would love to power health sensors off of body heat and then wirelessly transmit that data to wherever,” Grunlan explained. “You’d like to know if somebody had a concussion or was dehydrated or something like that while it’s happening in real time.”
As a person generates heat, the temperature outside is colder than what’s against the body. The temperature differential generates a voltage.
The goal is to design technology that can get one volt or up to 10 percent efficiency and beyond. So, for example, a researcher would try to get eight watts from a person who is generating 80 watts.
The ingredients in this thermoelectric recipe include carbon nanotubes, polymers and a carbon material called graphene, which is a nanoparticle.
Researchers are trying to perfect the recipe of this ink-like material.
“The one voltage is realistic, but how much material do we need to get that one voltage because we need as little as possible?” said Carolyn Long, a Ph.D. graduate student at Texas A&M.
“So, different polymers, different amounts of the multi-walled or double-walled nanotubes, adding the graphene, which order it needs to go in exactly to create the best pathway for the electrons for the thermoelectric material,” said Long of the various experiments she and her lab mates have conducted.
The aim is to create a product that can be mass produced.
“It will happen. It’s not will it happen. It’s when. Is it a year, or is it five years?” Grunlan said.
That will depend on how much funding and manpower is available to make this technology a reality.

Lizzy Maupa uses a bucket to transfer water she used to bathe from her tub to her toilet.
She has a four-week-old baby and a three-year-old child, but the city water supply has not been working for a month, says Maupa.
So she collects water from a nearby river, which she boils to drink. Maupa is being extra careful after Zimbabwe’s Ministry of Health on Thursday announced an outbreak of cholera in their part of the city.
“I have heard about it. I heard on the news last night,” she says. “So I am trying to be hygienic so that I can take care of the little ones. It has been difficult. I have too many water demands.”
Zimbabwe’s outgoing Health Minister David Parirenyatwa told reporters late Thursday approximately 40 people were being treated for cholera and five had already died from diarrhea and vomiting, typical symptoms of the water-borne disease.
During a visit to a temporary cholera treatment camp in Harare, he warned people to wash their hands and drink only clean water.
“It is usually a problem of contaminated water. These people were drinking water from, we suspect from one or two boreholes that our team has gone to take samples from,” he explained. “If they are contaminated, they will be decommissioned for now. Those that we have here are getting much, much better. As usual prevention, prevention, prevention is key otherwise we will have an outbreak throughout the country.”
A 2008 cholera outbreak in Zimbabwe lasted over a year and killed about 5,000 people.
It was stopped only after international groups like USAID donated drugs and water treatment chemicals.
The head of Zimbabwe Doctors for Human Rights Calvin Fambirai warns the country must improve basic sanitation to prevent further outbreaks.
“The conditions that necessitate the spread of cholera and typhoid in Zimbabwe haven’t changed,” he warned. “They are becoming worse by the day. The first problem we face is authorities haven’t been giving resources necessary for the improvement of service delivery in the country to make sure that these archaic diseases do not continue to break out.”
Poor hygiene, water quality and waste disposal in densely populated areas remain unsolved, notes Fambirai.
Residents often go for weeks without running water or waste collection.
Health Minister Parirenyatwa said the sanitation situation would improve a promise that many have heard before.

Early, partial results from a historic gene editing study in human patients that was released earlier this week give encouraging signs that the treatment may be safe and having at least some of its hoped-for effect, but it is too soon to know whether it ultimately will succeed. Faith Lapidus reports.
