Electrotherapy is the use of electrical energy as a medical treatment. [1] In medicine, the term electrotherapy can apply to a variety of treatments, including the use of electrical devices such as deep brain stimulators for neurological disease. [2]
Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it can move away by an electric current or electrical discharge . The word "static" is used to differentiate it from current electricity , where an electric charge flows through an electrical conductor .

Electrostatics is a branch of physics that studies slow-moving or stationary electric charges. Since classical times, it has been known that some materials, ...
Medical classification – A medical classification is a list of standardized codes used in the process of medical coding and medical billing. Medical coding – The practice of assigning statistical codes to medical statements, such as those made during a hospital stay.
The advantage of having an ER fluid which operates on the electrostatic effect is the elimination of leakage current, i.e. potentially there is no direct current. Of course, since ER devices behave electrically as capacitors , and the main advantage of the ER effect is the speed of response, an alternating current is to be expected.

Dielectric EAPs are materials in which actuation is caused by electrostatic forces between two electrodes which squeeze the polymer. Dielectric elastomers are capable of very high strains and are fundamentally a capacitor that changes its capacitance when a voltage is applied by allowing the polymer to compress in thickness and expand in area due to the electric field.
