Aigtek: 40kV High-Voltage Amplifier Powers New Breakthroughs in Dielectric Elastomer Experiments
Dielectric elastomers are considered one of the most promising "artificial muscle" materials and are widely used in soft robotics, smart prosthetics, tactile sensors, Braille displays, optical devices, aerospace, and energy harvesting. The working principle of dielectric elastomers is mainly based on their piezoelectric effect and dielectric properties. The input signal is amplified through an amplifier to drive the dielectric elastomer to generate an electric field. The change in the electric field leads to a change in the charge distribution within the dielectric elastomer, thereby causing its deformation or mechanical motion.
The ATA-7000 series from Antai Electronics is an ideal high-voltage amplifier that can amplify both AC and DC signals. It has a single-ended output of 40 kVp-p (±20 kVp) high voltage, capable of driving various high-voltage loads and empowering new breakthroughs in dielectric elastomer research experiments!
Application Case 1: Dielectric Elastomer Actuation Experiment
Figure: Schematic diagram of the dielectric elastomer actuation experiment
Experiment Process: The signal source outputs a sine wave voltage signal with a frequency of 1-10 Hz and an amplitude of 0-3 V, which is fed into the power amplifier. The power amplifier amplifies the signal to a voltage of 0-1500 V. The high voltage is applied to the conductive carbon paste on the positive and negative surfaces of the electroactive polymer. The conductive carbon paste accumulates opposite charges, generating an electrostatic force that squeezes the electroactive polymer to produce deformation.
Application Case 2: Dielectric Elastomer Performance Study

Experiment Process: A computer edits an arbitrary waveform, which is output by a function generator. The signal is amplified by the high-voltage amplifier to a voltage of 2 kVp-10 kVp, driving the contraction and expansion movement of the silicone rubber (dielectric elastomer) material. A laser sensor captures the waveform of the material's contraction and expansion movement. The movement waveform is transmitted through a wire to the computer. Using computer software, the input signal waveform and the waveform of the contraction and expansion movement can be observed. The two sets of data are compared. It can be observed that the material has a clear periodic expansion and contraction. The output waveform and the waveform of the contraction and expansion movement can be observed on the computer, and the two are completely consistent.
The ATA-7000 series of high-voltage amplifiers from Aigtek Antai Electronics has a wide range of applications in the fields of dielectric elastomers and electrostriction. The maximum output voltage of 40 kVpp can meet the testing requirements of most dielectric elastomers.
