Abstract: The present invention provides a chemo-resistive gas sensor in 5 which consists of two chemo-resistive sensor elements [16, 36] placed on both sides of a micro-hotplate array [26]. It is capable of providing lower power consumption compared to existing one-side sensing membrane gas sensor. An embodiment of the invention has the two sensor elements to be of same material to increase the sensitivity of the device. Another embodiment of the invention has two sensor elements of different material to allow different gas to be monitored. The proposed two membranes may be arranged to provide multiple gas solution for remote application and device miniaturization. Figure 1

Abstract: The present invention relates to a piezoresistive pressure sensor which detects applied pressure by measuring the change of electrical conductivity of the magnetic nanoparticles (3) in response to the application of mechanical stress onto the diaphragm (1). The pressure sensor comprises conductive electrodes (2) formed on the diaphragm (1) which is provided on a substrate (4). Magnetic nanoparticles (3) are deposited on the conductive electrodes (2) for electrically connecting the conductive electrodes (2) and changing electrical conductivity when stress is applied.

Abstract: The present invention discloses a micro check valve (100) for use in controlling the flow of fluid across a channel (160) in a micro-fluidic system, said valve (100) housed within a valve seat (140) and comprising a polygonal mass (110) connected to a base (120) through a resilient means (130). The mass (110) is a polygonal member with a predetermined thickness having a first side surface (101) exposed to the entry of fluid flowing in the channel (160), a second side surface (102) distanced apart and parallel to the first side surface (101 ), and having a longer length than the first side surface (101 ), a third side surface (103) and a fourth side surface (104) adjoining both ends of the first side surface (101) and the second side surface (102), said third side surface (103) and fourth side surface {104) disposed with a plurality of protruding dimples (106). Elastic deformation of the resilient means (130) due to pressure exerted on the mass (110) controls the flow of fluid across the channel (160), whereby establishment of a sealing contact between the mass (110) and the valve seat (140) blocks the flow of fluid across the channel (160) and a release of sealing contact between the mass (110) and the valve seat (140) allows the flow of fluid across the channel (160).
