Miniaturization of an Osmotic Pressure-Based Glucose Sensor for Continuous Intraperitoneal and Subcutaneous Glucose Monitoring by Means of Nanotechnology

open access: yesSensors, 2023
The Sencell sensor uses glucose-induced changes in an osmotic pressure chamber for continuous glucose measurement. A final device shall have the size of a grain of rice. The size limiting factor is the piezo-resistive pressure transducers inside the core

Compression induced intercellular shaping for some geometric cellular lattices

open access: yesBrazilian Archives of Biology and Technology, 2001
The wall perimeter fraction, which contact neighboring cells, was named compression ratio (alpha). A zero compression ratio indicates maximum intercellular (air) volume (vG, v/v) and neglectable contact among cells, while alpha=1 indicates complete ...

Bubble Chamber Pressure Gauge

open access: yesReview of Scientific Instruments, 1957
A description is given of the mechanical gauge and electrical circuit employed for measuring millisecond pressure pulses in a liquid hydrogen bubble chamber, in a pulsed magnetic field region. The pressure pulse produces a deflection of a diaphragm that acts as one electrode of a capacitor.

Application of control system considering pressure response of air cylinder for pneumatic stage

open access: yesNihon Kikai Gakkai ronbunshu, 2019
In the pneumatic stage, the differential pressure is the driving force. For this reason, it is indispensable for fast positioning to change the pressure in the chamber instantaneously. The piston in the air cylinder moves when the stage is driven.
