High-sensitivity low-power MEMS accelerometer for detecting extremely weak ground and building vibrations

16.02. 2018 Semiconductor Technology News - Semiconductor News, Semiconductors, Semiconductor Technology

Hitachi Ltd. today announced the development of a high-sensitivity low-power MEMS accelerometer that can detect extremely weak ground and building vibrations by combining sophisticated MEMS technology with circuit technology. The sensor achieves a comparable sensitivity to that of sensors for oil & gas exploration (noise level 30ng/√Hz) with less than half the power consumption (20mW). Hitachi intends to apply this sensor to various applications including next generation oil & gas exploration, and infrastructure monitoring, to contribute to the realization of a comfortable, safe and secure society.

Simulations reveal that atomic disorder from radiation can launch a cycle of self-healing in ceramic oxides

15.02. 2018 Condensed Matter News - Physics News, Physic Materials News, Physics, Materials

Scientists discovered a self-healing cycle for defects in ceramics predicted by advanced atomic-level simulations. Irradiation creates defects and causes the ordered atomic structure to become disordered. Simulations showed that creation of a threshold amount of disorder caused the displaced atoms to move faster. This sped up annihilation of the defects and healed the structure.
