Practical Applicability of Silicone Rubber Membrane Sodium-Selective Electrode Based on Oligosiloxane-Modified Calix[4]arene Neutral Carrier
Analytical Chemistry, 1995Co-Authors: Yutaka Tsujimura, Masaaki Yokoyama, Keiichi KimuraAbstract:Silicone Rubber-based Na + -sensing Membranes, which do not require any special plasticizer and are therefore quite resistant to Membrane deterioration, can be practically applied to Na + -selective electrodes, as far as the neutral carrier is highly dispersible in silicone Rubber. The silicone Rubber Membrane Na + -selective electrodes based on an oligosiloxane-modified calix[4]arene neutral carrier are reliable for sodium assays in human body fluids such as blood sera and urine. Two other Na + neutral carriers that are excellent ones for plasticized poly(vinyl chloride) Membranes did not give good results for silicone Rubber Membranes of the ion-selective electrodes, due to their poor dispersibility in silicone Rubber.

Comparison between silicone-Rubber Membranes and plasticized poly(vinyl chloride) Membranes containing calix[4]arene ionophores for sodium ion-sensitive field-effect transistors in applicability to sodium assay in human body fluids
Sensors and Actuators B: Chemical, 1994Co-Authors: Yutaka Tsujimura, M. Yokoyama, K. KimuraAbstract:Abstract Comparisons have been made between sodium ion-sensitive-field-effect transistors (ISFETs) based on silicone-Rubber Membranes and plasticized poly(vinyl chloride) (PVC) Membranes of highly dispersible calix[4]arene ionophores, regarding their applications to sodium assay in blood sera and urine. The silicone-Rubber Membranes are found to possess great advantages over the PVC Membranes on the application of their ISFETs to serum and urine samples. Hardly any potential deviation is found from sodium-ion calibration plots for the silicone-Rubber Membrane ISFETs on the sodium assay even of undiluted samples, whereas the deviation is serious for the plasticized-PVC Membrane ISFETs.

Oligosiloxane‐modified calix[4]arene ionophores for silicone‐Rubber‐Membrane sodium ion‐sensitive field‐effect transistors
Electroanalysis, 1993Co-Authors: Yutaka Tsujimura, Masaaki Yokoyama, Keiichi KimuraAbstract:Unsymmetrical and symmetrical calix[4]arene esters carrying oligosiloxane moiety were designed for neutral carriers of silicone-Rubber-Membrane sodium ion-sensitive field-effect transistors (ISFETs). The incorporation of oligosiloxane moiety to calix[4]arene ionophores promotes their dispersibility in silicone Rubber, thus bringing about high stability and low impedance of the ion-sensing Membranes and thereby high sensitivity and fast response of the resulting sodium ISFETs.

Design, fabrication, and testing of micromachined silicone Rubber Membrane valves
Journal of Microelectromechanical Systems, 1999Co-Authors: Xing Yang, Charles Grosjean, Yu-chong TaiAbstract:Technologies for fabricating silicone Rubber Membranes and integrating them with other processes on silicon wafers have been developed. Silicone Rubber has been found to have exceptional mechanical properties including low modulus, high elongation, and good sealing. Thermopneumatically actuated, normally open, silicone Rubber Membrane valves with optimized components have been designed, fabricated, and tested. Suspended silicon nitride Membrane heaters have been developed for low-power thermopneumatic actuation. Composite silicone Rubber on Parylene valve Membranes have been shown to have low permeability and modulus. Also, novel valve seats were designed to improve sealing in the presence of particles. The valves have been extensively characterized with respect to power consumption versus flow rate and transient response. Low power consumption, high flow rate, and high pressure have been demonstrated. For example, less than 40 mW is required to switch a 1-slpm nitrogen flow at 33 psi. Water requires dose to 100 mW due to the cooling effect of the liquid.

A MEMS thermopneumatic silicone Rubber Membrane valve
Sensors and Actuators A-physical, 1998Co-Authors: Xing Yang, Charles Grosjean, Yu-chong TaiAbstract:Abstract In this paper, a technology for fabricating silicone Rubber Membranes and integrating them with other processes on a silicon wafer has been developed. Silicone Rubber has been found to have exceptional mechanical properties, including low Young's modulus, high elongation, and good sealing. An integrated normally open valve using a silicone Rubber Membrane and 3M PF5060 liquid for thermopneumatic actuation has been fabricated and tested. For a 1.34 LPM (1 min −1 ) air flow, 280 mW power input is required to close the valve at 20 psi inlet pressure. Due to the high permeability of silicone Rubber, most liquids used in thermopneumatic systems will be lost, necessitating more work to find a suitable barrier material compatible with silicone Rubber.
