QorTek works in the fields of piezoelectronics and piezo actuation mechanisms. The company pioneered regenerative circuitry within power supplies, enabling recycling of the high amount of return energy experienced on each cycle when driving capacitive or inductive loads. The concept of regenerative power drivers for piezoelectric mechanisms was enthusiastically adopted by the engineering community and became the foundation for the companys success. QorTek later launched the development of novel sensor and actuator devices based on piezoelectric materials. Ensuing (regenerative) power products include: all-digital drives, hybrid drives, self-tracking drives, and capacitive drive systems. QorTek has expanded its technology base to begin a decade-long development of Intelliplastics® sensors and energy harvesting mechanisms. The interest in development of leading edge compact and subcompact power supplies for piezoelectric actuators led QorTek to develop its own mechanical amplified (flextensional) and bimorph actuator technologies. The company holds over 30 patents (with 10 more pending), and has completed more than 60 federaly funded R&D projects.
