Special Issue Information

Dear colleagues,

The manufacturing and integration of autonomous and embedded sensors through a combination of micro- and nano-system technologies have revolutionized self-powered, high-bandwidth devices for advanced manufacturing (AM), artificial intelligence (AI), Internet of Things (IoT), and health technologies.

More specifically, nano- and micro-electro-mechanical-systems (N/MEMS) sensors are the building blocks for a vast range of applications, from continuous real-time health (wearable) and environmental monitoring (gas, biomolecules, pressure, temperature, etc.) to enabling embedded mobile internet services (wireless), including smart/connected cars and unattended vehicles (UAVs) (inertial). As these devices are present in the tens of billions, the potential for disruptive innovation has been immense.

The integration of nano- and micro-sensors, which are functionalized using emerging materials to complementary metal-oxide semiconductors (CMOSs) and microfluidics systems, and their electro-mechanical packing, represents a challenge. This is because the integration and packing require the deposition of multiple layers of different dielectrics and metals, and the atomic mismatch between these layers, acting as an electron trap, increases ohmic resistance and detection time, creates noise, and reduces sensitivity, selectivity, and responsivity.

This Special Issue aims to introduce the manufacturing, packaging, and integration of autonomous and embedded sensors through a combination of micro- and nano-systems. Topics in general include, but are not limited to, the following:

  • Autonomous and embedded sensors: design, manufacture, packaging, and reliability;
  • Biosensors (photonic, electrical, chemical) and their integration into MEMS, CMOS, and microfluidic systems for COVID-19 and other (future) pandemic proteins/metabolites/analytes;
  • Sensor interconnectors/interfaces and their testing;
  • Graphene-based nano-sensors;
  • Electronic circuits for MEMS nano-sensor modulation;
  • Nano-electro-mechanical sensors.

This paper experimentally demonstrates a mode localization sensing approach using a single two-axis orthogonal resonator. The resonator consists of concentric multi-rings connected by elliptic springs that enable two orthogonal oscillation modes. By electrostatically tuning the anisotropic stiffness between the two axes, the effective coupling stiffness between the modes can be precisely controlled down to near-zero values. This allows the sensitivity of mode localization sensing to be tuned over a wide range. An order of magnitude enhancement in sensitivity is experimentally achieved by reducing the coupling stiffness towards zero. The resonator’s simple single-mass structure offers advantages over conventional coupled resonator designs for compact, tunable mode localization sensors. Both positive and negative values of coupling stiffness are demonstrated, enabling maximum sensitivity at the point where coupling crosses through zero. A method for decomposing overlapping resonance peaks is introduced to accurately measure the amplitude ratios of the localized modes even at high sensitivities. The electrostatic tuning approach provides a new option for realizing variable sensitivity mode localization devices using a simplified resonator geometry. Full article

In recent years, there has been significant interest in quantum technology, characterized by the emergence of quantum computers boasting immense processing power, ultra-sensitive quantum sensors, and ultra-precise atomic clocks. Miniaturization of quantum devices using cold atoms necessitates the employment of an ultra-high vacuum miniature cell with a pressure of approximately 10−6 Pa or even lower. In this study, we developed an ultra-high vacuum cell realized by a miniature ion pump using a high-efficiency plasma source. Initially, an unsealed miniature ion pump was introduced into a vacuum chamber, after which the ion pump’s discharge current, depending on vacuum pressures, was evaluated. Subsequently, a miniature vacuum cell was fabricated by hermetically sealing the miniature vacuum pump. The cell was successfully evacuated by a miniature ion pump down to an ultra-high vacuum region, which was derived by the measured discharge current. Our findings demonstrate the feasibility of achieving an ultra-high vacuum cell necessary for the operation of miniature quantum devices. Full article
