  "description_excerpt": "The present disclosure relates generally to mounting and securing consumer objects using electroadhesion. In particular, electroadhesion devices including a voltage control module for safely mounting consumer devices to target surfaces.\n\nMounting consumer devices to walls, furniture, trees, mirrors, windows, and other target surfaces can optimize existing device functions and provide new functionality. Once mounted, users of consumer devices including smartphones, tablets, cameras, streaming media players, and the like can easily view content and take pictures with others. Securely mounting a device also enables using the device without holding it and while multitasking. Additionally, secure mounting mechanisms minimize the instances where consumer devices are damaged or broken from falling from an unsecured location. There is therefore a need to develop a device holder that secures the device to a location, allows devices to be used hands free, and facilitates group interactions with devices. Previous attempts have been made to solve problems with mounting and securing consumer devices to target surfaces, but mechanical mounting mechanisms are unreliable and bulky. Mechanical mounting mechanisms also require time and effort to assemble and attach to a consumer device. Sometimes consumer devices can be damaged while attaching a mounting mechanism because screws, clamps, clips, and other components of the mounting mechanism can forcefully contact a screen or other fragile component of a consumer device and scratch, break, dent, or otherwise damage the consumer device.",
