Circuit design of IMU sensor and ESP32

For my research project am building a motion capture system to record biomechanical movement of human arm.
i have developed motion capture hardware using modules. now i want to convert it to a IC based custom circuit board.

I have to take IMU sensor values from multiple individual Sensors setup to a master controller.
Individual motion capture contains

ESP 32/ microcontroller
IMU sensor
3.7 Volt battery/ 3.3Volt battery
(any additional items required )
