Phys.org December 17, 2021 To create efficient energy storage solutions and actuators, engineers need materials with high dielectric constant. The current method of incorporating polar additives with a high dielectric constant has not yielded high enough dielectric constant for many applications. Researchers at Penn State University have demonstrated a new method for raising the dielectric constant by adding zwitterions, small molecules with one positive electrical charge and one negative electrical charge separated by covalent bonds. Zwitterions are non-volatile molecules that are highly polar. In their recent experiments, the team added the zwitterions to polymeric single-ion conductors. Zwitterions raised dielectric constant […]

Researchers use organic semiconductor nanotubes to create new electrochemical actuator
Phys.org September 3, 2021 To improve the movement and response time for electrochemical actuator devices that operate in liquid a team of researchers at the University of Houston has developed electrochemical actuator that uses specialized organic semiconductor nanotubes (OSNTs). The device demonstrated excellent performance, low power consumption/strain, a large deformation, fast response, and excellent actuation stability. The enormous effective surface area of the nanotubular structure which facilitates the ion transport and accumulation results in high electroactivity and durability. The work provides new opportunities for next-generation actuators that can be utilized in artificial muscles and biomedical devices…read more. TECHNICAL ARTICLE
