Alternate charging methods
Interesting post, Andy. Apart from efficient utilization of power, what do you think about alternate sources of charging when it comes to wearable technologies. Things like wireless charging and solar charging are being tested but are there any other ways you can think of or know about?

Re: Microprocessor for wearable Design
Typically, the Intel Quark features integrated security and SW stacks for security and connection of Internet design. This chip is approximately 5 times smaller and 10 times lower in power than Atom Processor.  At least there is comparison for size and power consumption between Quark and Qualcomm.

Re: Re : Wearable Technology: 3 Considerations for Super-Small Power Supply Solutions
Wearable technology, especially when it comes to devices and gadgets that function as IoT devices, is faced by many challenges but the one that really stands out (and indeed the one that is now giving most design engineers the real headache) is how to increase the power efficiency of the devices so that they can last and function for longer while at the same time trying to minimize the total board space on which the device is laid out. The above considerations should make the task a little easier though the headaches will still remain unless a new power source is developed soon.

Re : Wearable Technology: 3 Considerations for Super-Small Power Supply Solutions
The ultimate objective in the design of any item of wearable technology is the optimization of functionality and power efficiency so that the resultant device works better for longer. The first two factors mentioned in this article i.e. switching frequency and real-world power efficiency can both be achieved by careful and repetitive analysis while making the tradeoff between the board or circuit size and the eventual efficiency. I really love how you put this point across Andy.

Re: Microprocessor for wearable Design
@DaeJ >> ...Quark MCU...

It is hard for me to find a place for this SoC. It is too complex to integrate, requires too many different power supplies, requires too much PCB area for package and routing, consumes over 2W (theoretically) at only 400MHz, lacks several peripherals required for many wearable and/or embedded devices...

I don't see how Intel's Quark processors could get even close to be able to compete with ARM's Cortex A-Series processor implementations like Qualcom's, Freescale's or even TI's (see Sitara processors like this http://www.ti.com/product/am3358).

Nevertheless Quark processors are a step forward.

Re: Microprocessor for wearable Design
It will be a big challenge because the wearable technology holds big promises of becoming an high margin business and a wide range of diffusion among users for many purposes: fitness, medical,  safety etc...

Re: Microprocessor for wearable Design
@Daej Intel's Atom chips can't match ARM muscles in the market, that's where Quark comes in, Intel is tasking Quark platform for covering markets that traditonally use embedded microprocessors and other types of low power controllers.

Re: Microprocessor for wearable Design
Intels' challenge has been always about how to reduce power comnsumption, they hope that Quark could expand market Intel can go, Its Intel's fisrt major step into wearable space. But its going to be tough because they have plenty of competitors here- Qualcomm could be their biggest rival.

Microprocessor for wearable Design
Intel released Quark MCU to target wearable embedded application requiring small foot print and low power. This Chip could be used for medical industry, fitness and heath insurance. The below link provides more in detail:

This article explains how the latest-generation SiC FETs are ideally suited to new inverter designs with lower losses than IGBTs and proven robustness against short circuits, even at high temperatures and under repetitive stress
There’s a further cool thing you can do with a spreadsheet that most SPICEs can’t. That’s to use the spreadsheet ‘solver’ functionality to adjust component values in the search for a better-fitting circuit – or even to find a set of component values for a circuit you can’t otherwise design.
Infineon MOSFETs have been embedded into PC boards by Schweizer Electronic AG
You now need to adjust component values to achieve some system goal, such as predefined frequency response or time behaviour, and there’s no closed method for working out those values.
