“…However, reuse of the sensor was difficult because it was embedded and LAN has limited transfer distance. Kim et al [15] proposed a new temperature measurement method using the surface acoustic wave. Liu et al [16] improved the transfer distance of the embedded module using the embedded RFID sensor tag and outlined an economical system.…”

The systematic collection and management of on-site information in high-rise building construction are important factors in construction management. Recently, wireless sensor network (WSN) technology has been utilized to manage the various tasks involved in high-rise construction efficiently and in a timely manner. However, because of the repeated installation of sensors and repeaters along with the construction progress, the existing WSN technology is ineffective when applied to the temperature management of concrete in structural work. Here, we propose a new data collection method in which a worker uses a smartphone to repeatedly monitor concrete temperature. In field implementation, the proposed system enables concrete temperature management without a transmission gap for monitoring in 60-min intervals with smartphones provided to 20% of the structural workers. Next, a case study was performed on a high-rise building construction site to analyze the effectiveness of the proposed system in terms of cost savings by avoiding schedule delay. The results of the case study show that the proposed system can reduce the additional work costs resulting from delays in concrete curing and save up to $18,907 in labor costs. In addition, this system can reduce the temperature management time of the quality manager and enable more efficient management. It is also expected that this system will contribute to on-site waste management by reducing the number of embedded sensors.

“…However, the temperature of the concrete cannot be directly measured by the GPR technique. To solve this problem, a wireless and passive (no power supply needed) sensor designed by surface acoustic wave (SAW) delay lines [10][11][12] is used as the cooperative target. Since the piezoelectric substrate of the SAW sensor will convert an incoming electromagnetic signal into an acoustic signal whose velocity depends on the temperature of transducer, the phase of the echoes of the SAW sensor will be changed by the temperature variation of the concrete.…”

“…Surface acoustic wave (SAW) devices with interdigitated microelectrodes serving as interdigital transducers (IDTs) are commonly used in the information technology industry as electronic filters in delay line or resonator configurations [ 1 , 2 ]. A remarkable characteristic of SAW sensors is their sensitivity to a number of physical parameters, e.g., temperature [ 3 , 4 ], humidity [ 5 , 6 ], mass [ 7 , 8 , 9 , 10 , 11 ], and especially for the detection of (bio)chemical binding events on surfaces [ 8 , 9 , 10 ]. So far, SAW sensors are commonly used in two configurations.…”

Surface acoustic wave (SAW) devices are well known for mass-sensitive sensor applications. In biosensing applications, chemical and biochemically evoked binding processes on surfaces are detected in liquid environments using delay line or resonator sensor configurations, preferably in combination with the appropriate microfluidic devices. All configurations share the common feature of analyzing the transmission characteristic of the propagating SAW. In this paper, a novel SAW-based impedance sensor type is introduced which uses only one interdigital transducer (IDT), simultaneously as the SAW generator and the sensor element. Here, the input port reflection coefficient S11 is measured at the IDT instead of the commonly used S21 transmission forward gain parameter. Thus, a sharp and distinct peak of the S11 spectrum is obtained, enabling a comfortable direct readout of the sensor signal. Proof of the concept was gained by analyzing the specific binding of the 4-mercaptophenylacetic acid gold nanoparticles (MPA–AuNP) directly to the IDT surface. The corresponding binding kinetic of the MPA–AuNP on the functionalized gold surface has been analyzed and a sensitivity of 7.4 mΩ nM−1 has been determined.
