Claim:
1. A system comprising: a first chip including a first capacitive coupling element; a second chip including a second capacitive coupling element and a third capacitive coupling element, wherein the first chip and the second chip have different functions; and a ferrofluid droplet that acts as a spacer between the first chip and the second chip, wherein, in response to a magnetic field, the ferrofluid droplet aligns with the first capacitive coupling element and the second capacitive coupling element to create a first capacitor that includes the ferrofluid droplet for non-contact communication between the first capacitive coupling element and the second capacitive coupling element or aligns with the first capacitive coupling element and the third capacitive coupling element to create a second capacitor that includes the ferrofluid droplet for non-contact communication between the first capacitive coupling element and the third capacitive coupling element, wherein the ferrofluid droplet comprises a non-conductive liquid loaded with a plurality of magnetically reactive particles.
