Hello guys,
I would like to work using nRF52 as my processor to create products in the future, but I heard about Specific Absorption Rate (SAR) testing and that is good to know beforehand that the microcontroller/product could be suitable to be used for wearable applications and that if the device isn't suitable, it's possible that the design will be delayed for this, requiring change of the hardware, then software, then time, etc. I started to do some research I have not found no clear information about it so I would like to know if you could answer my doubts about it.
How can I select a microcontroller that could be used as a wearable device? what transmission parameters do I need to take care of? Does BLE modules are able to change their transmission power to be able to provide wireless communication in a wearable environment? (work within 20 cm to humans).
How can I understand better, or test, if my current application isn't enough to know if I am doing well for a future SAR testing/certification?
For example: Let's suppose that I want to use the nRF52840 DK dev board to start developing software for wearable devices, mainly as a hobby and to start learning about it and then move on to product development, but I want to know can I change their power transmission parameters to be able to pass SAR testing? Is there any software to test this? How to calculate an scope?
I hope this could work as a way to understand what I try to understand, is a bit of background about Specific Absorption Rate (SAR) for my future software development.
