Yes indeed it has to be taikored before it goes out to the public. COnsumesrs should be impressed by its quality and performance. - Kris Krohn

Duty Cycles, Activation for Use, and Recharging

I would think that considerable energy savings could be achieved by having the device active only when the user is engaging with it. Much of the time the device could be in a sleeping mode awaiting incoming data or user input. If the device isn't being worn, it could be in an even deeper sleep mode. Still, there needs to be a recharging plan.  Will the devices operate on a long life battery (like an electric watch) or will they have some mechanism to recharge overnight when not in use like a cell phone?

Harness energy from body and environment - no battery please

Wearables resides very much on our body. In that case they should adapt to get energy from our body and from what we eat. Or from environment.

Why do you need to embed battery in wearables? You need only little enrgy storage device and it must learn to harness enrgy very much like living culture like flora and fauna.

Very good point @_hm...but how do we tap to the energu we consume via food?...I remember readng about glucose harvesters, but by definition they need to get implanted somewhere in your body and get the energy out from there, not a pleasant solution even if it works...the most simple is to tap to the temperature difference between the body and environment but this only works in cold climate or air conditioned rooms...Kris

@Krisi: Yes, it may be way to innovate something. Temperature and infrared may be obvious. But there can be more intricate chemical type enrgy harvester.

But the biggest enrgy available from our body is by movement or kinetic energy.

Yup.  And has been harnessed by "self-winding" watches that have been around for more than 200 years.

@zeeglen: Why can not it replace battery?

No reason why movement/kinetic energy cannot replace a battery, or keep a battery or supercap charged.  Your point is valid, I was agreeing with you.  But also pointing out  that such energy harvesting is a proven technology that has been used for a long time and therefore would most certainly be viable in today's applications.

Good point @_hm...I forgot about MEMs mechanical harvesters...although you have to move and we usually sit in fron of the computer or drive, not much movement I am afraid...Kris
