electrostatic
an electric field/charge that is stationary
electrostatic
an electric field/charge that is stationary
capacitor
a device that stores electrical energy between two conducting electrodes separated by a dielectric (nonconducting) material
Maxwell pressure
when a voltage is applied between electrodes pressure arises, the elastomer contracts in thickness and expands in area.
dielectric breakdown
occurs when current flows through a material whose electric charges do not flow freely
hydraulically amplified self-healing electrostatic (HASEL) actuators
A device which generates movement from electrical energy. The device consists of liquid segments which helps amplifying force generation and heals itself in case of an electrical breakdown.
actuation
the action of causing a machine to operate
hydraulic
denoting, relating to, or operated by a liquid moving in a confined space under pressure.
soft robotics
a subcategory of robotics that deals with the construction of flexible robots to mimic living organisms
soft actuators
a lightweight, affordable, and easily customizable device component consisting of flexible material that converts energy into mechanical movement in order to move/control a part of the device
polymer
AP Chemistry
Essential knowledge 1.A.1 (EK1.A.1)
Molecules are composed of specific combinations of atoms; different molecules are composed of combinations of different elements and of combinations of the same elements in different amounts and proportions.
density
AP Physics II
Fluids: Essentials Knowledge 1.E.1
Matter has a property called density.
electric field
AP Physics II
Essential Knowledge 5.B.2
A system with internal structure can have internal energy, and changes in a system’s internal structure can result in changes in internal energy. [Physics 1: includes mass-spring oscillators and simple pendulums. Physics 2: includes charged object in electric fields and examining changes in internal energy with changes in configuration.]
actuation strain
deformation produced by a non-mechanical stimulus
elastomer
a material that produces a large deformation when a voltage is applied
polymer fibers
man-made fibers consisting of synthetic chemicals
transducers
a device that converts an energy signal in to another form of energy signal
an example of this is mechanical energy being converted to electrical energy
ionically conductive polyacrylamide (PAM) hydrogels
a gel which contains significant amount of water and can conduct electricity
electrodes
an electrical conductor that makes contact with nonmetallic parts of a circuit
polydimethylsiloxane
the most widely used silicone based organic polymer
strain
the ratio of total deformation to the initial dimension of the material body upon application of external forces.
dielectric permittivity
this ability of a material to hold an electrical charge
fluidic actuators
a device component which uses hydraulic fluid pressure to convert energy into mechanical movement in order to move/control a part of the device.
