Smart materials are a class of materials having one or more properties that can be signifi cantly changed in a controlled manner by changing the external stimuli, such as stress, temperature, moisture, pH, electric, and magnetic fi elds. There are numerous types of smart materials; however, we can categorize them on the basis of their responsive behaviors during the stimuli. " Piezoelectric materials " are ceramics or polymers characterized by a swift, linear shape change in response to an electric fi eld. The electricity makes the material expand or instantly contract. This class of materials has potential applications in actuators to control chatter in precision machine tools, improve robotic parts for faster and accurate movement, microelectronic circuits in machines (e.g., computers, photolithography printers, etc.), and also in integrity -monitoring fi bers for bridges, buildings, and wood utility poles [1] . " Electrostrictive and magnetostrictive materials " show a change in material size with response to either an electric or magnetic fi eld, and conversely produce a voltage when stretched. These materials show promising applications for the manufacturing of pumps and valves, aerospace wind tunnels, shock -tube instrumentation, landing gear hydraulics, and further biomechanics force measurement of orthopedic gait and posturography, sports, ergonomics, neurology, cardiology, and rehabilitation [2] . " Rheological materials " are smart materials that include not only solids, but also fl uids like electrorheological and magnetorheological fl uids that can change state instantly using an electric or magnetic fi eld [3] . These types of fl uids being used as dampers for vehicle seats, shock absorbers, exercise equipment, and optical fi nishing. " Thermo -responsive materials, " such as shape memory alloys, show a change in shape in response to heat and/or cold. Nitinol or nickel and titanium are usually combined to form such intelligent materials. The rarely used materials for this class are Au/Cd, Ag/Cd, Cu/Al/Ni, Cu/Sn, and Cu/Zn/Al [4] . They are frequently used in couplers, thermostats, and automobile, plane and helicopter parts. " pH -sensitive " materials are used as indicators and can change color as a function of pH. This type of smart material shows promise in paints

“…Potentiometric method has been considered as an attractive detection method because of the cheap and simple instrumentation required, commonly a pH-meter (Situmorang, et al, 2008). Tungsten metal electrode due to its responsive to potential changes has been used as sensing device, and its compatible for sensing component has been demonstrated in the construction of potentiometric sensor (Situmorang, 2001). Tungsten electrode has also been used as transducer for potentiometric biosensors with immobilization of enzyme in polytyramine for malic acid (Situmorang, et al, 2001).…”

It was demonstrated that electrodeposited polytyramine (Situmorang, et al, 1999) could act as a substrate electrode and retain its ability to determine potential change (Situmorang, et al, 2002).…”

The development of mercury ion selective electrode (ISE-Hg) by using ionophore 7,16-Di-(2-methylquinolyl)-1,4,10,13-tetraoxa-7,16-diazacyclooctadecane (DQDC) in an electrode membrane sensing is explained. The study is aimed to construct an ion selective electrode for mercury by immobilization of ionophore DQDC in a polymeric PVC membrane electrode. Membrane electrode was constructed by casting and spin coated methods from the mixture of DQDC and plastisizer in a polymeric PVC matrix dissolved in a tetrahydofuran solvent. The membrane has been characterized and used as a sensing material in an ISE-Hg. The developed ISE-Hggive sensitive and selective response to mercury, working range linearity lies between 0.005 mM -1.0 mM Hg 2+ , slope 25.82 mV per decade concentration of Hg 2+ (r 2 = 0.998).
