A method for producing stretchable, bio-compatible metal electrodes that can be soldered to conventional electronic devices is reported in Nature Communications. This could allow realization of flexible medical devices such as electrocardiogram sensors.

Sang-Hoon Lee and colleagues developed a stretchable electrode that can withstand repeated strain of up to 20% with minimal reduction in performance. They addressed a major challenge in the integration of flexible and conventional electronics by demonstrating that the electrode can be soldered to rigid electronic devices. They also used the electrode for bio-sensors which were applied to the skin or implanted in mice, showing lack of irritation to the tissues.
