Controlling an object with a hand gesture sounds more like Jedi wizardry than a real-life possibility. But after watching a CES 2021 demo of the Mudra Brand, I have to admit that perhaps this tech isn’t as far-fetched or gimmicky as I previously thought.
The Mudra Band looks pretty much like any smartwatch band would, except that the inside lining has several square-shaped Surface Nerve Conductance (SNC) sensors. These sensors measure something the company refers to as “biopotentials”—basically, the electrochemical activity produced by your nervous system. Fundamentally, this is the same concept used by more familiar tech like ECGs, albeit for a much different purpose.
