Home » Science » Tiny Electric Motor Inspired by Ancient Water Pump Operates at Molecular Scale A groundbreaking advancement has been made in molecular electronics with the development of a tiny motor that operates at the molecular scale, inspired by an ancient water pump. International researchers have engineered a screw-shaped molecule capable of rotation driven by an electric current, leading to enhanced current flow that can increase by up to 100 times. Upon applying a voltage, the molecule exhibited cyclic motion with a discernible directional preference. Altering the polarity of the voltage reversed the direction of the rotation, allowing researchers to have dynamic control over the motor’s movement without physical intervention. The findings suggest that the positions the molecule avoids while at rest offer the best pathways for electrical conduction, only becoming accessible…
