Medical Device Force Measurement Applications

4D Bioprinting

Interface load cells help researchers analyze material behavior during printing, optimizing biocompatible implants’ functionality. During medical R&D, load cells used in medical device prototypes can detect pressure or tension within the printed construct. 4D printing for bioprinting utilizes 3D printing techniques to create functional structures. Forces and stresses need to be measured during the printing process. Interface’s SuperSC S-Type Miniature Load Cell has a high force in a compact design and can easily record the forces of the printhead during the printing process. To record and analyze the load cell’s force data, utilize a data logger, such as Interface’s 9330 Battery Powered High-Speed Data Logging Indicator with a USB port and software. Measuring forces can provide valuable data on the material’s behavior during printing to identify swelling or degradation. Learn more.

Radiosurgery Robot

Radiosurgery is a medical procedure that uses targeted radiation to remove cancerous tumors or masses in the body. Radiosurgery robots, a medical device surgical tool, target these abnormalities and deliver radiation minimally invasively with high precision and accuracy. Load cells are needed to test and calibrate the robotic arm before it affects a patient. Interface’s 6A40A 6-Axis Load Cell can be installed at the joints of the radiosurgery robot. The force and torque exerted must be monitored to ensure each robotic joint can handle the precise movements and loads without failing. These results can be logged, displayed, and measured when connected to Interface’s BX8-HD44 BlueDAQ Series Data Acquisition System with included BlueDAQ software. Learn more.

Prosthetics Load and Fatigue Testing

Interface force measurement sensors provide valuable insights into prosthetic foot mechanics, enabling design improvements for enhanced mobility and comfort. Prosthetic limbs must be tested for extreme loading, which can occur during falls, accidents, and sports movements. Fatigue testing of prosthetic components determines their expected lifespan under normal usage. A static load test apparatus uses an SSMF Fatigue Rated S-type Load Cell attached to hydraulic actuators to apply and measure loads. A fatigue testing machine uses a miniature load cell to measure cyclic loads during force application. Engineers determine whether prosthetic materials and designs will withstand the rigors of daily use and occasional high-load situations.

Force measurement is an essential tool for medical device innovation. Researchers, engineers, designers, and manufacturers can leverage cutting-edge technology and expertise by partnering with Interface to develop safe, effective, life-changing medical devices.

As the healthcare industry continues to evolve, Interface remains committed to providing solutions that empower medical device companies to push the boundaries of possibility and improve patient care.
