Conclusion

32

• BLE connected wearables were

discussed; highlighting a wearable

SoC with integrated charger, audio

support and many other sub-systems.

• Future trends will include continuous

increase of processing power, security

and increased integration of sensors

and other wearable sub-systems.

• Wearables will for some time still be

(also) on the wrist… but who knows

where and how they will end up on our

bodies…
