A capacitor provides a plurality of selectable capacitance values, by selective connection of six capacitor sections of a capacitive element each having a capacitance value. The capacitor sections are provided in a plurality of wound cylindrical capacitive elements. Two vertically stacked wound cylindrical capacitance elements may each provide three capacitor sections. There may be six separately wound cylindrical capacitive elements each providing a capacitor section. The capacitor sections have a common element terminal. A pressure interrupter cover assembly is sealingly secured to the open end of case for the elements and has a deformable cover with a centrally mounted common cover terminal and a plurality of section cover terminals mounted at spaced apart locations. A conductor frangibly connects the common element terminal of the capacitor section to the common cover terminal and conductors respectively frangibly connect the capacitor section terminals to the section cover terminals. Deformation of the cover caused by failure of the capacitor element breaks at least some of the frangible connections sufficient to disconnect the capacitive element from an electric circuit in which it is connected. A cover insulation barrier mounted on the deformable cover, has a barrier cup substantially surrounding the common cover terminal and a plurality of barrier fins each extending radially outwardly from the barrier cup, and deployed between adjacent section cover terminals.

Tunable electronic units and associated systems, as well as methods for tuning characteristic properties of soft electronic units (e.g., inductance, capacitance, and resistance) and fabricating soft tunable planar inductors, axial inductors, capacitors, and resistors, are provided. Disclosed systems and methods enable standardized tuning of different types of soft electronic units (e.g., including a soft inductor, capacitor, and resistor, etc.), and enable remote tuning while maintaining a tuned value without expending power. In certain embodiments, electrical properties of the soft electronic units are tuned using a mobile component (e.g., ferrofluid and iron powder) dragged with a permanent magnet inside a soft fluidic channel. This may be used for applications and devices which need to be soft and flexible, such as implantable electronics, wearable devices, and skin electronics.

A button device includes a MEMS sensor having a MEMS strain detection structure and a deformable substrate configured to undergo deformation under the action of an external force. The MEMS strain detection structure includes a mobile element carried by the deformable substrate via at least a first and a second anchorage, the latter fixed with respect to the deformable substrate and configured to displace and generate a deformation force on the mobile element in the presence of the external force; and stator elements capacitively coupled to the mobile element. The deformation of the mobile element causes a capacitance variation between the mobile element and the stator elements. Furthermore, the MEMS sensor is configured to generate detection signals correlated to the capacitance variation.
