One aspect of the present disclosure relates to a remotely controllable lens device. The lens device can include a lens material and a circuit physically coupled to the lens material. The circuit can be configured to be powered based on an energy signal from a power source to perform a function (e.g., release of drug, generation of electromagnetic radiation, detection of electromagnetic radiation, and/or control of an optical refractive property). For example, the power source can be an external power source and/or an auto-powered source. The external power source can be, for example, a power source that utilizes synchronized magnetic flux phase coupling (e.g., WiTricity). The auto-powered source can be provided on-site (e.g., on-chip) using a harvesting system (e.g., solar-cell, photo-cell, piezoelectric, etc.)

Remotely controllable lens device

Provided are a method of manufacturing a flexible device and the flexible device, a solar cell, and a light emitting device. The method of manufacturing a flexible device includes providing a device layer on a sacrificial substrate, contacting a flexible substrate on one side surface of the device layer, and removing the sacrificial substrate. A large area device may be transferred onto the flexible substrate with superior alignment to realize and manufacture the flexible device. In addition, since mass production is possible, the economic feasibility may be superior. Also, when a large area solar cell having a thin thickness is manufactured, since a limitation such as twisting of a thin film of a solar cell may be effectively solved, the economic feasibility and stability may be superior.

Provided is a method for separating a nanogenerator, which includes laminating a buffer layer on a sacrificial substrate, making a nanogenerator on the buffer layer, laminating a metal layer on the nanogenerator and separating the nanogenerator from the buffer layer. Here, a nanogenerator is separated by using a stress difference between the sacrificial substrate and the metal layer, instead of an existing method in which a nanogenerator is separated from the sacrificial substrate by means of wet etching or the like. In particular, according to a difference between a tensile stress at the metal layer such as nickel and a compressive stress at the lower silicon substrate, the nanogenerator is intactly separated from the silicon oxide layer serving as a buffer layer. Therefore, the nanogenerator may be separated from the sacrificial substrate in a mechanical way, which is safer and more economic in comparison to an existing chemical separation method using an etching solution. Further, it is also possible to avoid a damage of the nanogenerator caused by an etching solution.
