Hackaberry Feedback System

Problem Statement

Prosthetic hands like the Hackberry allow amputees to grasp objects, but they lack sensory feedback, making it hard for users to gauge grip strength or object temperature. This results in unsafe or awkward interactions with everyday objects, reducing autonomy and user confidence.

About Hackaberry Feedback System

Solution

  The Hackberry Feedback System enhances the 3D-printed Hackberry hand by integrating force and temperature sensors. These additions allow users to receive real-time tactile feedback while grabbing objects, simulating a more lifelike sensory experience. Key Features: Force-Sensing Resistors (FSRs) on the thumb and palm detect grip strength. A temperature-sensitive resistor on the palm provides heat feedback. All sensors are connected to a microcontroller that processes and relays feedback in real-time. This system is a significant improvement to the original Hackberry hand, offering amputees more control and sensory awareness during daily tasks.
