Force Sensors

Definition

Force sensors are devices that measure the amount of force applied to them, providing critical data for various applications, including prosthetics and rehabilitation. These sensors convert mechanical force into an electrical signal, which can then be used to monitor and adjust the function of prosthetic devices, ensuring a more natural interaction with the user’s environment. By enabling real-time feedback, force sensors play a vital role in enhancing the usability and effectiveness of assistive technologies.
