摘要： An electrochemical device includes an electrochemical cell and an electric circuit. The electrochemical cell comprises a first solid component and a second solid component. The two solid components comprise same chemical elements but have different concentrations of at least one type of the chemical elements. A solid electrolyte is arranged between the two solid components. The solid electrolyte is a dielectric material. The electric circuit is connected to the electrochemical cell. The electrochemical cell may be operated according to a redox process, so as to exchange chemical elements of the at least one type between the first solid component and the second solid component and thereby change an electrical conductance of each of the two solid components.

摘要： An artificial cochlea device for processing audio signals by electro-mechanical amplitude changes may be provided. The device comprises a micro-electro-mechanical system (MEMS) microphone comprising a membrane, an electro-mechanical feedback loop embedded in the MEMS microphone. Thereby, the electro-mechanical feedback loop comprises a piezo-electric actuator acting on the MEMS microphone by influencing the membrane's way to swing, such that an electro-mechanical amplitude change of an output signal is achieved.

摘要： Embodiments of the disclosure are directed to a lateral current injection electro-optical device. The device comprises an active region with a stack of III-V semiconductor gain materials stacked along a stacking direction z. The active region may be formed as a slab having several lateral surface portions, each extending parallel to the stacking direction z. The device further comprises two paired elements, which include: a pair of doped layers of III-V semiconductor materials (an n-doped layer and a p-doped layer); and a pair of lateral waveguide cores. The two paired elements may be laterally arranged, two-by-two, on opposite sides of the slab. The elements distinctly adjoin respective ones of the lateral surface portions of the slab, so as for these elements to be separated from each other by the slab. The disclosure may be further directed to related silicon photonics devices and fabrication methods.

摘要： A tunable resistive element includes a first terminal, a second terminal and a resistive layer having a tunable resistive material. The resistive layer is arranged between the first terminal and the second terminal. The resistive element further includes a piezoelectric layer having a piezoelectric material. The piezoelectric layer is adapted to apply stress to the resistive layer. An electrical resistance of the tunable resistive material is dependent upon a first electrical control signal applied to the first terminal and the second terminal as well as upon the stress applied by the piezoelectric layer to the resistive layer. The stress applied by the piezoelectric layer is dependent on a second electrical control signal applied to the piezoelectric layer.
