Researchers have developed a new solar powered battery, capable of changing its shape to fit various flexible forms.
The team says the battery could transform the wearables market by lowering the space required for a battery, a big benefit for e-skin and e-clothes products.

The components are electronically connected via flexible copper-polymer interconnects, mounted on a highly elastic silicone core, and enclosed within a silicone shell, the team said.
The authors demonstrated the use of these systems for continual logging and wireless transmission of body temperature data in a variety of realistic scenarios, such as monitoring skin temperature during physical exercise and bathing, and measuring temperature changes during breathing.
The battery may also be a welcome addition to the e-skin market, with researchers recently creating a much longer lasting tattoo that changes color and can even track things like UV rays and heart-rate.
Wearables are still a young market, but with 67 percent growth from 2015 to 2016, more companies are starting to see the potential of devices able to gather more data on the customer.
