What's the best solution for body area network

[abcyxjk]

I am PHD student in china and doing research about gait retraining. I am designing wearable sensor that monitoring gait and giving vibration feedback to retrain the gait and I want it wireless. But I am not familar with wireless technology and don't know which chip I should choose.

I need 8 sensors, each sensor need send 18 Bytes each package with 100Hz sample rate and should able to receive some feedback commands sometimes. The system should run in real-time, so the delay must low than 0.2s.

I find a product said using Nordic Semiconductor nRFL01 + radio, ultra low power, which I think actually is nRF24L01. That system have 15 small sensors and a very big receiver. That system is what I want to design. www.apdm.com/.../

Who can help me? Thanks!

I develop two products that can be used for the purpose,
Insoles. By integrating FSR(Force Sensing Resistor) and IMU, the insoles can detect plantar pressure and foot posture. I choose nrf chip to send data to cellphone or PC, so it can be used for gait analysis. The insoles integrate wireless power charging and antenna either, which looks similar to an ordinary insole from the appearance.
This solution can also be applied to shoes. If interested, you can refer to: https://zhuanlan.zhihu.com/p/2020121495549002419.

Tag. It can be mounted on the belt to detect body posture. IMU is integrated acommpany with nrf chip, wireless power charging and antenna are implemented either.
