However, the pressure to keep down the costs of all parts used in domestic appliances is omnipresent and also applies to the area of sensors and microsystems. The lifetime of sensors, sometimes under adverse conditions, is critical, and a lifespan between 8 and 15 years should be expected. Commercially viable prices for sensing modules are rather low, depending on the individual functions, but less than 5 Euro for a complete module are typical [1]. Also the financial risk involved in serial production has to be considered. Just one faulty unit would cost the producer nearly 100 Euro to repair, even if this unit costs only 2 Euro. If the factory output is 2000 units per day, the loss may amount to 20 million Euro if a flaw is detected by one of the customers after 100 days of production. 

Hadjidemietriou [25] used an Orion Model 93-07 nitrate ion-selective electrode with a 1 x 2 sensing module construction, and an Orion Model 90-02 double junction reference electrode fitted on a pH meter. The outer chamber was filled with 0.04 M ammonium sulfate solution and the inner chamber with Orion 90-00-02 solution.

Finally, other considerations for the sensing module are to avoid hardened metal cases or brackets as these do not have inherent damping and will have higher resonant peaks than soft metals. 

The autocrine growth enhancing and toxin neutralizing effect of toxin related polyethers such as gamberic acid-A and brevenal suggests a possible role in quorum sensing modulation.

This concept of communication-regulated cell growth and death could facilitate the cooperation of a natural quorum-sensing module with engineered counterparts and thus confer beneficial functions to engineered cells. Moreover, this approach can help balance populations of cells in bioprocessing consortia. 

The thermocapacitive flow sensor is based on a dielectric material with a temperature-dependent dielectric constant. The sensing module is a capacitor. If the electric power is supplied to a heater that is close to the capacitor, the temperature of the capacitor will increase, causing an increase in the dielectric constant and, thus, an increase in the capacitance of the capacitor. When a fluid flows through the capacitor and if its temperature is lower than that of the capacitor, the temperature of the capacitor will decrease due to the convective heat transfer between the fluid and the capacitor. The temperature of the dielectric material of the capacitor will decrease, resulting in a decrease in the... 

The sensing module is a capacitor, which has a dielectric layer, whose dielectric constant increases with temperature. In practice the capacitor module can be fabricated using a MOS-compatible process combined with... 

The sensing modules developed in [15] were attached to the connectors, as shown in Fig. 27.8. These ribbons can be shifted up and down the wearer s limbs and can be secured with yarn. Due to the sensors being physically similar to the ones used in the woven jumpsuit with an on-fabric network garment, the communication structure is similar. The sensor nodes are located on approximately the same points on the body as they were in the jumpsuit with the woven on-fabric network the torso and the midpoint of each limb segment (upper arm, forearm, thigh, and shin) [1,10,15].
