Paper Title:
An Efficient Low-pH Range Sensitive Artificial Muscle for Future Active Implantable Systems
  Abstract

Based on recent experiments made by the present authors on a “pH-muscle” functioning in an admissible physiologically pH-range, a global analysis is developed for a future “artificial muscle implant” both safe and efficient. A scheme of a possible future artificial muscle implant is shown associating our current prototype, whose skeletal muscle-like behaviour is provided by McKibben artificial muscle technology, with the use of a bio-compatible micro-organism, to be specified, which would be able to generate the necessary ionic-strength change to the swelling and de-swelling of the ion-sensitive agent placed inside the McKibben structure. Preliminary experimental results are reported of a 10 cm long artificial muscle and 8 mm external diameter filled with a RCOOH commercial Amberlite resin generating a maximum force of 80 N with buffer solutions of pH between 4.5 and 8.4 in some tens of minutes with the hope of obtaining quicker responses by use of more specific ion-sensitive polymers.
