Abstract
A power-generating laminate for an airship comprises a base fabric layer, a barrier layer disposed upon the fabric layer, an inner metal film layer disposed upon the barrier layer, a piezoelectric/pyroelectric layer disposed upon the inner metal layer, an outer metal layer disposed upon the piezoelectric/pyroelectric layer, and a cover layer disposed upon the outer metal layer. The power-generating laminate forms a gas-impervious envelope to maintain lifting gas and air therein, and is configured such that when the envelope is subjected to structural strain or experiences changes in temperature, power is generated, which is used to supply power to the various electrical systems aboard the airship.
