bendy battery gives smart fabrics a charge - lithium iron battery
Paul MarksA's flexible battery can be unobtrusively woven into the fabric and one day it can power the gadgets in your clothes.
When a flat flexible battery is connected to T-
The shirts have flashing LEDs array on them, but they are not built into the material of the clothes.
Maksim Skorobogatiy of the Montreal Institute of Technology, Canada, and his colleagues said they had done so.
To build their batteries, they embedded solid polyethylene oxide electrolyte between the lithium iron phosphate cathode and the titanium lithium anode.
All of these are thermoplastic materials that can be stretched under mild heating (
Journal of the Institute of Chemistry, DOI & colon; 10. 1149/2. 020204jes).
This material looks like artificial leather.
After stretching, the team woven cotton strips into cotton cloth and connected these batteries in series using conductive threads.
This configuration is used to illuminate the led.
"This is the first fully wearable soft lithium battery-
"Ion batteries that do not use liquid electrolyte," Skorobogatiy claims . ".
He said that clothing made of this material can provide hundreds of volts, thus realizing the battery-
In case of emergency, the clothes lined with the back can provide electricity.
"We have enough power to send out powerful distress signals and even to save lives by allowing the patient to defibrillation through the defibrillator," he said . ".
The team now faces a more common challenge.
Waterproof technology and make it washable.
Sandy Black, who studies smart textiles at London's Fashion Institute, believes that bags, backpacks and medical supplies --
Clothing can be monitored first using this technology.
"I think the critical mass is reached across the region.
Things in the mainstream can't be too far away.
