Stretchable Batteries: Arrays of Ultracompliant Electrochemical Dry Gel Cells for Stretchable Electronics (Adv. Mater. 18/2010)

The front cover illustrates an ultracompliant battery for powering stretchable electronic items useful in wearable and comfortable electronic items integrated into clothing or implants. The battery combines acrylic elastomers with functional gel electrodes and withstands stretch ratios up to 100%. Shown is a series connection of two batteries, sufficient for driving a green light-emitting diode. More details can be found in the article by Siegfried Bauer and co-workers on p. 2065.
