Princeton Docket # 10-2585


             Researchers at Princeton have developed a new design for highly flexible, high output piezoelectric assemblies.  Princeton is seeking an industrial partner to commercialize this technology.


            Current and past devices have relied on low output piezoelectric compounds and mechanical linkages in an attempt to perform a similar function.  This new device uses lead zirconate titanate (PZT) crystals transferred onto a flexible substrate, then encased in a polymeric sheath to isolate the lead compound.  This greatly increases the comfort factor in wearing such a device, as well as the number of potential applications.


It is anticipated that this new device can be used for applications for generating power from bodily functions such as walking, breathing, and movement, as well as attached to any moving mechanical part where on-the-spot generation of small amounts of electrical power would be useful, such as powering or recharging phones, computers, camera systems, body assist devices such as pacemakers and defibrillators, and for military applications for maintaining weapons systems power from body motion or recoil.  These devices are superior to solar cells in that they can operate in darkness, indoors, or in less-than-optimal lighting conditions.


Patent protection is pending.
