Study of Electrostatic Actuator Voltage Reduction with a Tri-Electrode Actuator with Varying Pull-Down Voltage

Proceedings, 2018
Employing a tri-electrode topology for electrostatic actuators can significantly reduce needed control voltages. The tri-electrode topology employs a perforated intermediate electrode between the MEMS structure and pull-down electrode, and provides a low

Tracking Health Related Quality of Life From Diagnosis to Follow‐Up Among Australian Children With Acute Lymphoblastic Leukaemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Acute lymphoblastic leukaemia (ALL) is one of the most treatable forms of paediatric cancer; however, there is a substantial burden of treatment‐related toxicities (TRTs). In addition, the long‐term changes in children's health‐related quality of life (HRQoL) due to toxic treatments are not well understood.

Pull – in analysis of L – shaped meandered capacitive pressure sensor at ultra low pressures

e-Prime: Advances in Electrical Engineering, Electronics and Energy
Pressure sensors in the range of 0 – 100 Pa are used in medical ventilators to monitor and control the air pressure delivered to patients during breathing assistance. They ensure precise control of low-pressure airflow in respiratory support systems.
