The WT9011 should be able to send sufficient data. Practical in that it has iOS SDK, so very familiar territory for the author. However the battery life is very bad at 8 hours, the cost of transmitting continuously the raw samples... It would be a rather simple hack to increase that by 3-4x, at the expense of added bulk. As it is a standard LiPo cell inside. Device itself is very small, and has charger integrated. I did a quick mechanical review of this device last week. Have not checked the software yet.
