First Claim
1. An electric switch apparatus, comprising:
- a base comprising a first channel and a second channel, wherein the base comprises a flexible polymer and a strain-dependent gate coupling the first channel to the second channel;
an electrode disposed in the first channel, wherein the electrode comprises a cavity and a liquid metal disposed in the cavity; and
an electrically insulating liquid at least partially disposed in the second channel, wherein in a strained condition a portion of the electrically insulating liquid extends into the first channel dividing the electrode into at least two electrically isolated chambers within the first channel, and wherein in an unstrained condition the cavity of the electrode is undivided.

Abstract
An electronic switch apparatus, a capacitive strain gauge apparatus and a nozzle apparatus, as well as methods for making electrodes such as liquid metal pipes are provided. A nozzle apparatus includes (a) a nozzle housing defining a cavity, where the nozzle housing defines an inlet at a first end and defines an outlet at a second end and (b) a first tube defining an inlet at a first end and defining an outlet at a second end, wherein the first tube is at least partially disposed in and is co-axially arranged with the nozzle housing, where the first tube defines a first flow channel, wherein a second flow channel is defined between an exterior surface of the first tube and an interior surface of the nozzle housing.
