From the project
60-sensor wearable with flexible PCB and pressure matrix
OpenMuscle FlexGrid is a modular wearable sensor grid with 60 analog pressure sensors arranged in a 15x4 matrix. It is the second-generation wearable in the OpenMuscle series and serves as the core interface for capturing muscle movement in prosthetic and robotics applications.
- Sensor Grid: 15 columns × 4 rows of Velostat pads - Flex PCB: Thin and wearable with 21-pin output header - Rigid PCB: ESP32-S3, haptic feedback, USB-C charging, multiplexer, OLED, IMU
