Revolutionary Electro Mechanical Polymer Actuators

Strategic Polymers develops cutting edge technologies for electro mechanical actuators.  The core building blocks are revolutionary and proprietary Electro Mechanical Polymers (EMP) and the knowhow to create the world’s thinnest high performance EMP actuators. 

EMP actuators are the world’s thinnest actuators. EMP actuators vibrate and deform, are ultra light, high strain, cost competitive and customizable.  No other actuator technology competes with so many characteristics.

  • Ultra thin, less than 50μm
  • Ultra light, less than 1.0g
  • Highly flexible, bends (180 degrees) 
  • Robust
  • Fast response time, less than 1ms
  • Drive voltage, less than 150V
  • Low cost
  • Optimal response in the acoustic frequency range
  • Optimal response in the tactile frequency range

 

 The Science of Electro Mechanical Polymer (EMP) Technology

Strategic Polymers EMP offer a unique combination of high strain and high mechanical modulus brought about by the high electrostrictive response of the EMP.  

When an electric field is applied to an EMP actuator, polarization changes cause the polymer to lengthen in high strain stretching. 

The result is electrostrictive effect rather than electro static force. Due to this the mechanical modulus can be 100 to 1000 times higher than competitive polymer actuator technologies.

EMP technology is highly scalable and EMP actuators can be customized to meet your actuation needs and requirements.
