Wearables #1: Wearable textile battery can be recharged by sunlight
Energy Storage seems to be the point of intersection of the future.
Going hand in hand with the development of wearable electronic textiles, researchers are also pushing the development of wearable and flexible energy storage to power those e-textiles. […] Going one step further, a research team in Korea has now developed wearable textile batteries that can be integrated with flexible solar cells and thus be recharged by solar energy. eporting their work in the October 28, 2013 online edition of Nano Letters (“Wearable Textile Battery Rechargeable by Solar Energy”), the team demonstrates a fully functional wearable textile battery by finding unconventional materials for all of the key battery components and integrating them systemically: Nickel-coated polyester yarn as a current collector for efficient stress release, polyurethane binder for strong adhesion of active materials, and polyurethane separator with superior mechanical, electrochemical, and thermal properties.
Wearables #2: study looks at the acceptance of wearables
As scientists develop the next wave of smartwatches and other wearable computing, they might want to continue focusing their attention on the arms and the wrists. According to a recent Georgia Tech study, portable electronic devices placed on the collar, torso, waist or pants may cause awkwardness, embarrassment or strange looks.
In a paper titled “Don’t Mind Me Touching My Wrist,” Georgia Tech researchers reported the results of a case study of interaction with on-body technology in public. Specifically, they surveyed people in both the United States and South Korea to gain cultural insights into perceptions of the use of e-textiles, or electronic devices, stitched into everyday clothing. […] In general, the study found that in both countries, the wrist and the forearm were the most preferred locations for e-textiles, as well as the most normal placement when watching someone use the devices.
