Bournemouth University (BU) in the UK, in collaboration with the University of Cambridge and China University of Geosciences, has developed a new method for improving battery life in wearable technology.
The paper states that "the new architecture can be utilised as a binder-free electrode, and presents extraordinary mechanical flexibility and outstanding electrical stability under external stresses".
"The new method ... uses a novel 3D structure approach to bind the electronic materials to the clothing textiles," Associate Professor Amor Abdelkader from BU said.
"We found that this new structure made a real difference to the mechanical strength of the battery, including increasing its flexibility under stress, which is important for the development of wearable technology. Clothing designed for the military or elite sportspeople, for example, needs to be able to perform under extreme conditions."
According to BU, the new battery will be more effective than previous prototypes, while also being more sustainable. The process of making the battery will also use fewer materials, making it easier to manufacture.
"For the wearable technology industry, this is a really significant step forward, and opens up the potential to develop the next generation of wearable devices in clothing," said the study's lead author Dr Kai Xi of Cambridge University.
Tonya Hall and David Blodgett, chief scientist of the research and exploratory development department at Johns Hopkins University Applied Physics Lab, talk about creating a wearable brain-computer interface while discussing the ethics of mind reading.
