Smartwatch 'smart straps' died for a reason. I still want them to come back.

Samsung and Pebble tried and failed to fill watch bands with modular tech. I still love the idea, no matter how impractical it is.

We haven't seen tech-filled watch bands since the early days of Pebble and Galaxy Gear, but Polar's modular tech has me curious if this abandoned idea deserves a renaissance. Think of the Double Tap feature made popular with the Apple Watch, only with much better accuracy because these bands can read the signals from your brain, knowing that you intend to make a pinching motion even if your fingers barely move. More straightforward smart straps with feature additions or battery enhancements sound pretty neat in theory, but a bit too impractical and costly to the consumer for companies to invest in the idea.
