Components
Raspberry Pi Zero 2W
parses muscle signal data and runs GPT API. connects to microphone devices via Bluetooth for user input.
Arduino Uno Rev3
receives muscle sensor data. acts as an analog-to-digital converter(ADC)for Pi. future versions will not use an Arduino and only an ADC for size considerations.
GPT-4
LLM to generate responses. custom GPT used to ensure responses fit concisely on user interface and only supported response types are generated.
Coming Soon …
Custom Casing
3D printed shell allows for component housing while giving electrodes access to skin.
MyoWare 2.0 Muscle Sensor
collects forearm EMG data. future versions will use dry electrodes for easier application and no sensor pad replacement criteria.
Wisecoco 6 inch Flexible OLED
1 mm thick flexible OLED matches forearm curvature and displays vibrant color.
Coming Soon …
Onboard Battery
rechargeable battery gives all day* usage.
*exact battery life range TBD.
Compression Sleeve
removable from casing + machine washable.
