Breakthrough MEMS Huygens clock improves timekeeping precision and stability

Breakthrough MEMS Huygens clock improves timekeeping precision and stability

(Press-News.org)

In a significant development for the miniaturization of electronic devices, a new study published in Engineering has reported the creation of a Microelectromechanical Systems (MEMS) clock that offers improved precision and stability. The clock, which utilizes the synchronization principle discovered by the Christiaan Huygens, consists of two synchronized MEMS oscillators and a frequency compensation system.

The research details how the MEMS Huygens clock enhances short-time stability, with the Allan deviation – a measure of the clock’s accuracy over time – improving by a factor of 3.73 from 19.3 ppb to 5.17 ppb at 1 second. The clock's long-term stability is also significantly boosted, with the Allan deviation improving by 1.6343 × 105 times to 30.9 ppt at 6000 seconds.

To achieve these results, the researchers developed a frequency compensation system that counteracts the MEMS oscillator’s temperature-frequency characteristics, thereby maintaining the clock’s accuracy by controlling the resonator current. This innovation led to a highly efficient method of compensating for frequency shifts in both oscillators simultaneously, consuming just 2.85 mW∙°C−1.

The study’s comprehensive solution scheme paves the way for high-precision MEMS oscillators and expands the application scope of synchronization in MEMS technology. With the continuous shrinking of electronic components, this breakthrough offers promising prospects for industries relying on precise timekeeping, such as telecommunications, navigation, and data processing.

As the demand for more accurate and reliable timing sources grows, the MEMS Huygens clock presented in this study stands to make a substantial impact on the future of microelectromechanical systems and their integration into everyday technologies.

HKUMed’s world-first ‘Liver-in-Cube’ wins a gold medal at International Exhibition of Inventions of Geneva, advancing precise cancer treatment
2024-06-12
Background Liver cancer is the sixth most common cancer and third leading cause of cancer death globally. According to Hong Kong Cancer Registry data, there are approximately 1,800 new cases of liver cancer each year, with over 1,500 deaths, over 80% of which are advanced cases at first diagnosis. Patients with advanced liver cancer who are not suitable for surgical operations have limited treatment options. Traditional chemotherapy, targeted therapy and immunotherapy for treating advanced liver cancer often have a low response rate and severe side effects, thereby limiting their efficacy and hindering the patient’s quality ...

Nationwide zonation and durability assessment of China’s plateau infrastructure under freeze–thaw cycles

Nationwide zonation and durability assessment of China’s plateau infrastructure under freeze–thaw cycles
2024-06-12
In a bid to tackle the enduring problem of infrastructure durability in the face of relentless freeze–thaw (F–T) cycles, a team of researchers has published a new study in Engineering. The study focuses on the Chinese Plateau region, where the harsh effects of F–T cycles on concrete structures have led to concerns regarding their aging and subsequent performance deterioration. The authors of the study emphasize that the existing national standards for designing frost-resistant concrete structures are insufficient, as they rely primarily on the coldest monthly average temperature without accounting for the intricate spatiotemporal variations, amplitude, and ...

Quantum dots and metasurfaces: Deep connections in the nano world

Quantum dots and metasurfaces: Deep connections in the nano world
2024-06-12
In relationships, sharing closer spaces naturally deepens the connection as bonds form and strengthen through increasing shared memories. This principle applies not only to human interactions but also to engineering. Recently, an intriguing study was published demonstrating the use of quantum dots to create metasurfaces, enabling two objects to exist in the same space.   Professor Junsuk Rho from the Department of Mechanical Engineering, the Department of Chemical Engineering, and the Department of Electrical Engineering, ...

Researchers at Houston Methodist find survival improves with open radical hysterectomy in early-stage cancer

2024-06-12
Early-stage cervical cancer patients see better survival and decreased recurrence rates after open radical hysterectomy than minimally invasive laparoscopic approaches, according to a 5-year study led by Houston Methodist researchers and published in the Journal of Clinical Oncology. “The findings from this and an initial study in 2018 led to the change in the National Comprehensive Cancer Network guidelines established that same year that for radical hysterectomy we routinely perform an open approach. This latest study reaffirms this recommendation,” ...
