The layer of the RLP® device that allows for activation under a voltage load (or vice versa) through piezoelectric response is the PZT component, which is a RoHS-compliant lead zirconate titanate ceramic material. These PZT components are brittle materials by nature, and thus their ability to perform mechanical work under applied load as standalone devices is limited. The AdaptivEnergy RLP® is an acronym for “Ruggedized Laminated Piezo”, which by definition is a piezoelectric actuator designed to withstand rough usage through implementation of a lamination process.
AdaptivEnergy’s RLP® Advantages
Achieving a strong bond in the RLP® composite device is a critical requirement in order to obtain proper functionality and longevity for actuators and harvesters, as the bond strength and bond temperature work to ensure proper ceramic stress bias. AdaptivEnergy has designed and incorporated a proprietary polymeric bonding system into the RLP®, which provides for obtaining the ideal ceramic stress state and unmatched device reliability at high temperature and humidity…all this with process cycle times and temperatures proven cost effective for high volume manufacturing.
Advantages of the RLP® device include its cost, scalability, unmatched reliability, and high volume manufacturing capabilities.
