Revolutionary Stretchy Battery Could Soon Power Pacemakers and Hearing Aids

Rapid summary

• Scientists at Linköping University in Sweden have developed a flexible, stretchable battery capable of retaining power even when bent or deformed.
• The battery incorporates modified lignin (organic material), nanographite, and silver nanowires to achieve its flexibility while preserving functionality.
• It uses fluid electrodes that behave like toothpaste and can be shaped using 3D printing to accommodate diverse designs and applications.
• It provides potential applications for wearable technology, medical devices like insulin pumps and pacemakers, e-textiles embedded with electronics, and soft robotics mimicking human-like movements.
• The battery is rechargeable over 500 cycles without losing performance. It operates at 0.9 volts but researchers aim to enhance its voltage capabilities through further studies.
• While promising, experts highlight the need to ensure the materials’ non-toxicity for prolonged contact with human skin.
