I currently have a project that has integrated sensors to monitor human health and related biomarkers, my domain is human-performance so giving athletes the tools to get better at their respective game.
I have recently begun trying to gather information regarding bioimpedance in order to implement this in my embedded project. For a prototype I am using the STM32 series ( blue pill chip ) to package a sensorframe of values ( o2, pulse, gyro & acc data, temperature ) now I really want to add bioimpedance to this device - heres what I think I know so far anyways
We need to emit an electric current over a multi-channel ( I want to calculate bone density, muscle mass, fat mass)
We need an emitter and a receiver
there needs to be two connected components by a wire that connect the two devices that complete the circuit
My questions are this, what frequency do I need to use to calculate my targets?
