  • Shock-Protection Improvement Using Integrated Novel Shock-Protection Technologies

    This paper presents the design and results of shock experiments conducted to demonstrate the advantages of two novel shock-protection technologies: 1) nonlinear spring shock stops and 2) soft coating shock stops. Both technologies basically employ the conventional idea of hard shock stops to decouple device design from shock-protection design but are specialized to reduce impact force, which is one of the drawbacks of hard stops. In addition, they enable wafer-level and batch fabrication processes compatible with microfabrication techniques. We designed test devices to reflect the effect of impact force and fabricated them using silicon microbeams (nonlinear springs) or Parylene coating (soft coating). After conducting multiple shock tests (up to 2500 g), we demonstrate that the shock-survival rates of test devices are considerably improved in both our novel technologies (nonlinear spring: 88%, soft coating: 94%) compared to conventional hard stops (4%). Moreover, we demonstrated that shock protection is improved by optimizing the design of shock springs. Finally, we analyzed dynamics of flexible beams and identified a new device-fracture mechanism induced by impact force, which is different from conventionally known mechanisms.

  • Micromachined integrated shock protection via a self-adaptive nonlinear system

    An original design of a self-adaptive nonlinear system (SANS) for shock protection of MEMS is presented here for the first time. The internally integrated passive silicon structure, with increasing amplitudes of shock, realizes nonlinear growth in shock resistance and reveals positive selectivity and compatibility, through three energy dissipation modes. This approach enables a generic batch fabrication requiring no additional processes or excessive area expansion (290μm×320μm for an 8cm×8cm device in this work). The SANS has been verified to provide enhanced shock robustness over conventional shock protective structures, namely the hard stop (~2 times) and the flexible spring stop (~1.5 times).

  • Shock protection based on confined self-adjusting carbon nanotube arrays

    We demonstrate a novel shock protector based on confined self-adjusting carbon nanotube (CNT) arrays. The CNTs with self-adjusted length are selectively synthesized on fully fabricated single crystal silicon microstructures to generate coulomb damping. The frictional contact between CNT arrays dissipates energy during impact and thus reduces the impact force applied on microstructures. The outstanding mechanical flexibility and resilience of CNTs make them suitable as a contact material that effectively absorbs energy through frictional contact preventing mechanical failure of microstructures. Experimental shock tests verify that CNT-based shock protector provides substantial survival rate of movable proof-mass compared with hard stop or compliant spring stop.

    A control problem for a system of finite number of masses connected by means of nonlinear spring elements is considered. This problem is reduced to control problems for independent one-degree-of-freedom linear oscillators.

  • Shock Protection Using Integrated Nonlinear Spring Shock Stops

    This paper reports the fabrication and testing of integrated nonlinear spring shock stops to protect micromachined devices. This approach enables a generic batch micro-packaging technology providing superior shock protection over conventional hard shock stops, and can be conveniently integrated with micromachined devices without additional fabrication processes and excessive area expansion. These advantages are demonstrated by integrating the nonlinear spring shock stops with a capacitive and with a piezoresistive MEMS accelerometer fabricated by different processes. Conducted shock tests reveal that the nonlinear stops provide substantial device survival rate (83%) compared with hard stops (8%). The device fracture mechanisms are also identified

  • A novel shock protection method based on MEMS compliant latching stopper

    This paper reports a novel shock protector on the basis of compliant latching system for the shock resistance enhancement of microelectromechanical systems (MEMS) devices applied in high shock environment. For the first time, MEMS latches have been employed to dissipate energy during impact. Through the machine logic, the MEMS latches have realized different shock protection functions upon relative impact amplitudes to reduce the impact force applied on microstructures. In this work, the compliant latching stopper has been verified to provide multi-fold shock resistance improvement compared with some traditional shock protection structure such as hard stopper and compliant spring stopper.

  • Novel integrated shock protection for MEMS

    This paper reports the design and analysis of two novel concepts for shock protection of MEMS devices using nonlinear springs and soft coatings. Hard shock stops have conventionally been used for shock protection for MEMS devices, but their operation generates secondary impacts and unwanted device oscillations. The two concepts described herein aim to improve shock protection by reducing secondary impacts and dissipating energy. We analyze the merits and demerits of each concept using simulation methods and also suggest ranges of shock stop design parameters to enhance performance. Doing so reveals that the nonlinear spring shock stops are capable of reducing impulses by over 90% while soft coatings may reduce impulses by 40%.

  • Shock-protection of nano-gap capacitive MEMS accelerometers using sloped electrode design

    This paper presents a novel sloped electrode scheme to enable the implementation of shock stops in MEMS devices that use a sacrificial layer to define in-plane capacitive gaps. Since the thickness of the sacrificial layer grown or deposited on the sidewall of a microstructure is constant, by sloping the interdigitated fingers, one can get a larger travelling range for the proof-mass than the thickness of the sacrificial layer. This allows the realization of larger sensing gap than the shock stop without using additional photomasks or fabrication steps. Proposed scheme is incorporated into the accelerometer design with 270 nm gaps and number of different characterizations were done to verify the survivability of the sensor under high-g environment. Further characterization shows a scale factor of 55.3 mV/g, noise density level of 187.09 μg/√Hz at 1 Hz for devices with a full- scale range of +/- 16g.

  • Shock protection with a nonlinear spring

    Using the simplest case of a nonlinear spring with a cubic restoring force, we show that a hard characteristic might be advisable for structural elements which are able to withstand high accelerations (decelerations), while the maximum displacement has to be made small by any means. Application of a spring with a soft characteristic can result in appreciably lower maximum accelerations (decelerations) than in a linear system; therefore, such application can be recommended in the case when the requirement for the lowest displacement possible is not very stringent. However, if the maximum drop height is not known with certainty (which is typically the case) the advantages of a soft spring cannot be utilized to a full extent, because of the possibility of a "rigid impact". In such a case (which occurs if the initial potential energy of the element is too high and significantly exceeds the work of the restoring force within the actual "breaking distance"), a probabilistic approach can be effectively used to design a soft spring with a low enough probability of a rigid impact. The obtained results can be helpful when designing spring protectors for vulnerable structural elements in portable electronics. These results can be useful for a rather broad class of nonlinear springs, not necessarily with cubic restoring forces.<<ETX>>
