To confirm the ImPULS remains fully functional, we measured the displacement of the ImPULS before and after 7 days of aging test. As shown in Fig. 2g (right), the displacement of the device degrades only 2.4% in 7 days. In order to simulate the potential use of the ImPULS as a ...
Harmonic oscillations as well as a unit jump or a unit impulse are used as test signals for the determination of the system parameters. For reasons of operating safety, these signals are not often tolerated. Random irregular vibrations are present in all systems and the repetition of these natur...
To test that an ImPULS remains functional over a long period of use within a harsh biological environment, we tested the durability of the ImPULS by performing an accelerated aging test in a phosphate-buffered saline (PBS) solution at an elevated temperature of 75 °C for 7 days (Supplement...
