Polydimethyl siloxane (PDMS) is one of the most widely used materials for academia to prepare microfluidic test devices. This has also motivated the development of roll-to-roll imprinting towards the fabrication of PDMS-based devices at high volumes. The gas bubble entrapping during the replication process has remained an issue resulting in defects in the microstructure. Performing imprinting in vacuum is a well-known method to avoid bubbles but it has not been applied in roll-to-roll processing. In this work we demonstrated a reduced ambient pressure roll to roll imprinting process using PDMS silicone elastomer as imprint resist. We observed the reduction in the number of bubble-originated defects in individual micro-features from 100 % to < 1 % when the ambient pressure was reduced from 1 atm to 1/8 atm.

The electromagnetic actuator, which serves as an auxiliary component in nano-g MEMS accelerometers for improving the dynamic response, faces the challenges of process incompatibility, temperature sensitivity, and large form factor. Thereby, this paper proposes an area-changed capacitive method for both displacement transducing and force balance in a nano-g MEMS accelerometer, aiming to address those posed challenges and provide favourable performance. Thanks to the allowed large displacement range in the sensitive direction of the proposed device, the area-changed capacitive mechanism is able to be integrated with a highly-sensitive quasi-zero stiffness spring-mass structure. As a result, the fabricated force-balance MEMS accelerometer attains a calibrated self-noise of 1.3 ng/\u0000<inline-formula> <tex-math>$surd $ </tex-math></inline-formula>\u0000Hz, which is one of the most sensitive MEMS-based accelerometers reported to date. The settling time, on the other hand, is reduced to 0.5 s with the electrostatic closed-loop control featuring the proposed subject, compared to 15.7 s in the open-loop configuration. In addition, the critical acceleration input at the boundary of the “pull-in” is calculated as 5.4 g, which is adaptable to most geophysical applications. This work is of considerable potential in geophysical applications such as earthquake monitoring or gravity measurements, and promising a high-performance closed-loop MEMS accelerometer.

The core component of the gyroscope is the micro-hemispherical resonator (MHR). The inevitable frequency split of the MHR working modes will directly restrict the performance improvement of the gyroscope. Therefore, it is crucial to eliminate the frequency split by a tuning method. A femtosecond laser ablation method is reported for permanent frequency tuning of the wineglass modes in MHRs with teeth-like tines. Firstly, the influence of different positions and depths of the tuning ablation grooves on the eigenfrequencies and frequency split of the working modes is determined by theory and simulation. In the low-frequency rigid axis, the efficient tuning method is located at the outer edges of the tines, while closer to the middle of the tines can obtain a more accurate frequency split. In addition, the Laser Doppler Vibrometer (LDV) test system has been built to test the frequency split of the MHR. Femtosecond laser ablation experiments were then designed, and the experiments and simulations were in good consistency. Finally, combined with the test system and the tuning method, the frequency split of a MHR is reduced to one percent of the initial, which is helpful for the gyroscope’s performance.

To achieve a target stiffness value via closed-loop control in a timeframe that is practical for most metamaterial applications, it is necessary that such actuators can rapidly respond to the controller’s commands. In this letter, a fabricated thermal actuator experimentally demonstrates the ability to achieve desired stiffness values within 100s of milliseconds of receiving the command signal. The actuator can also maintain those stiffness values regardless of changing external loading conditions with acceptable accuracy. Thus, the results of this work prove that the metamaterial design can enable practical applications such as surgical tools that can change from compliant to stiff states as they perform their functions within the body and materials that can tune their natural frequencies to enable technologies that leverage resonant actuation such as steerable mirrors and optical switches.
