4th World Congress on Biomimetic, Artificial Muscles and Nano-Bio Life Time of Trilayer Actuators Based on Polypyrrole

Artificial muscles based on polypyrrole films doped with ClO4 had demonstrated movements up to 180 degrees in LiClO4 aqueous solution which are controlled through the applied electrical current. Movements of this type are achieved with currents from 10 mA. The current density and its polarity control the rate and the movement ́s direction of the artificial muscle[1, 2]. Besides, bilayer and tril...

Artificial muscles based on conducting polymers

Natural muscles have mechanical properties that conventional actuators do not possess. These natural machines show large strain, moderate stress, high efficiency and stability, fast response time, high power/weight ratio, long lifetime, etc. In the last years a great interest has arisen to develop materials that mimic natural mechanisms. Conducting polymers have an array of potential applicatio...

A Polypyrrole-based Strain Sensor Dedicated to Measure Bladder Volume in Patients with Urinary Dysfunction

This paper describes a new technique to measure urine volume in patients with urinary bladder dysfunction. Polypyrrole - an electronically conducting polymer - is chemically deposited on a highly elastic fabric. This fabric, when placed around a phantom bladder, produced a reproducible change in electrical resistance on stretching. The resistance response to stretching is linear in 20%-40% stra...
