In recent years, the research on soft robots has become a hot spot in the field of robot research. Because the 

freedom of soft materials can be freely changed according to demand, soft robots have extremely high flexibility, 

and soft robots have good human-computer interaction performance and safety due to the softness of their 

materials. Its appearance successfully solves the problem of insufficient human-machine interaction and narrow 

scope of application of traditional rigid robot. At the same time, the soft robot can also complete some irregular 

work, which the traditional rigid robot can not do anyway. Soft robots have broad application prospects in medical 

field, military field, disaster relief field, biomedical field and family service field.

Soft robots, as the name suggests, are made of materials that are necessarily soft. It is thanks to its soft materials 

that soft robots can have extremely high degrees of freedom and good human-machine interaction. In addition 

to softness, the manufacturing materials of soft robots should also have good plasticity and high elasticity.

In the manufacturing process of soft robot, one of the most important parts is the high voltage amplifier. Dielectric 

elastomer (DE) is a new type of electroactive polymer (EAP) material which can produce large deformation under 

the excitation of external voltage. The DE material used as a driver usually has a sandwich structure. The flexible 

electrodes on the upper and lower surfaces of DE material will accumulate positive and negative charges under 

the action of electric field. Under the action of electric field force, the DE film will compress in the direction of 

thickness and expand and deform in the direction of plane. When the external force or voltage is withdrawn, the 

DE material will return to its original shape. In this process, the DE material realizes the conversion of electrical 

energy to mechanical energy. Because of its characteristics of large deformation, fast response speed, high 

energy density, light weight and low cost, DE material has been widely used in the manufacture of soft robots. 

So it is of great significance for the study of DE materials.

Wisman high voltage amplifiers are often used in DE material research. AMW series high voltage amplifiers 

have a maximum output power of 400W and a maximum output voltage of ±20kv to meet the needs of different 

flexible electrode voltages. AMW High Voltage Power amplifiers, High Voltage amplifiers, Wisman High voltage 

power supplies are launched for industrial and research applications. All solid state high voltage insulation design, 

can achieve high conversion rate, broadband and low noise operation. Four-quadrant active output absorbs or 

outputs current to a reactive or resistive load over the entire output voltage range. This type of output is 

essential to achieve accurate output response and the high conversion rates required for various loads, such 

as highly capacitive or reactive loads.
