I am very new to freescale and sensory technology. I am an ecologist, and work with hummingbirds in the forests of Ecuador. I am trying to understand how hummingbirds use energy in the wild to determine what limits where a species can and cannot exist. It would be great if I could implant them with accelerometers and/or heart rate monitors and/or GPS sensors. I know these are all very different things, but I'd love to explore the possibilities. I would use these to record how much of their time they spend flying (and how fast, if possible), vs. resting.
The main problem is their size- they weigh between 2 and 20g, which is the minimum weight of most of the accelerometers I've found so far online. Would it be possible to get one which is a fraction of a gram's weight, so that I could attach it to a ~6g hummingbird without restricting its movements?
Look forward to hearing from you all!
