ImpactModerate impact

The discussions highlight the potential for this technology to advance fields like micro-force measurement and drug delivery, suggesting a moderate to high impact.

Abstract in brief

  • An open-source force analyzer using a DVD optical pickup unit has been developed to measure tiny forces from 11 N down to 0.99 nN, addressing the limitations of traditional methods like texture analyzers for microNewton-scale measurements.
  • The device employs adjustable cantilever force transducers with steel shim magnets and 3D printed parts, making it versatile for different force ranges, and it successfully validated its use in measuring mucoadhesive forces on porcine tissues and microdrug devices.
  • This technology can help improve the development of small-scale oral drug delivery systems and has potential applications across various fields requiring precise force measurements at micro- to nano-scale levels.
