Telemetry is the process of remote data collection and transmission. The necessary components for telemetry are sensors and small monitoring systems. These components need little or occasional power input but from a reliable power source and usually sustain over a long period. The Plant-MFC meets these demands. It can provide the power in situ and is nearly maintenance free contrary to batteries that need replacement. Since the Plant-MFC is nonintrusive and only dependent on vegetation, temperature and soil saturation, the technology can power telemetry systems in all wetlands, estuaries and water bodies in temperate climates. This would allow for continuous monitoring without the use of an external power supply, such as a battery. There are several papers on the use of sediment MFCs or plant MFCs as a power supply for telemetry systems. They provide examples of monitoring weather conditions, water quality, pollution events and biodiversity.
Water Quality Measurement

In the past, the better instruments may have had a self-storing data system, usually in the form of paper graph or a retrievable magnetic tape. Although this allowed for continuous sampling, it was not without problems. The ease of obtaining data, in situ data gathering, and digital data acquisition are all attributes that are attractive in environmental applications. New technology has made these wishes a reality. For example, radio telemetry is a wireless technology to link remote sensors to dedicated computers or Supervisory Control and Data Acquisition (SCADA) systems. This capability allows for truly automated data acquisition and real-time uplinks. Other systems can be hardwired to computers (usually via RS 232 boards) or through modems to a remote acquisition site.

Telemetry is a form of communications whereby monitoring data is sent remotely to other equipment. Global positioning system (GPS) technology has been available for decades on construction vehicles to monitor location and enable satellite navigation. That provided some basic data on logistics, for example, tonnage per hour for quarrying trucks. As vehicle engines developed with computer management systems, so the type and volume of performance data increased, with information on service diagnostics and pollution emissions.

Recently, there is growing interest in using wearable devices for biomedical telemetry applications such as cardiac and glucose monitoring, diagnostic of neurological and oncological diseases, or therapeutic applications in order to improve the quality of the human life. Wearable device, in essence, is a wireless device equipped with an antenna, a transmitter, sensor/s and a processor, and can be mounted on the human body or embedded in clothing [1]. Such device can be used to provide a wireless connection between an implanted device (in-body communication) and an external device (off-body communication) for transmitting telemetry data. The antenna is an essential part of each wearable device and biomedical telemetry system, respectively, because the antenna and radio wave propagation constitute the core elements of the in-, on-and off-body wireless channel [2,3].

Walking economy (VO2; ml kg−1 min−1) was measured during submaximal treadmill exercise (Woodway, Model PPS 55) to derive individual oxygen uptake (VO2) versus heart rate regression equations. Oxygen uptake and carbon dioxide production (VCO2) were measured breath-by-breath using a Cortex Metalyzer (Leipzig, Germany). Exercise heart rate was measured continuously using radio-telemetry (Polar technology, Kempele, Finland). The treadmill speed was set at 1.5 m s−1 (3.3 mph) and remained at this speed for the duration of the test. The initial gradient (0%) was maintained for 4 minutes and at the end of this and each subsequent four-minute period the gradient was increased by 4% (to 4%, 8%, 12% and 16% respectively). During minutes 3–4 at each gradient a rating of perceived exertion (RPE) value was recorded (6–20 scale; Borg, 1982) and a blood sample was obtained by finger-stick to determine the blood lactate concentration (Biosen; EKF Diagnostics, Cardiff, UK). After a short, period of passive recovery (10 minutes) participants performed a test to determine the maximum oxygen uptake (VO2max) using a modified protocol (Balke & Ware, 1959). In the latter test, the treadmill speed remained at 1.5 m s−1 while the treadmill gradient increased 2% every minute until 20%. Thereafter, the treadmill speed increased 0.13 m s−1 (0.3 mph) every minute until volitional exhaustion.
Railway wheel tread damage and axle bending stress – Instrumented wheelset measurements and numerical simulations

The telemetry module on the axle is powered via an induction power head installed on the gearbox frame that induces a high-frequency alternating current in the inductive coil installed on the axle just below, see Figure 1. The telemetry module acquires data from four strain gauge full-bridges and processes the signals according to the rainflow count algorithm before storing the data in matrices (one matrix per strain gauge). The matrices are transmitted by telemetry to an on-board PC module by means of a 2.4 GHz radio connection. The strain gauges were placed 80 mm from the wheel seat, where the effect of the stress concentration near to the wheel seat fillet radius is negligible. In the present installation, two telemetry modules (each consisting of two full strain gauge bridges) were installed so that axle bending stresses could be monitored at regular angular intervals of 45 degrees (0º, 90º, 225º and 315º). Here, it is assumed that each strain gauge bridge is capable of detecting the mean value and amplitude of the bending strain along one diametrical line of the axle cross-section. A sketch of the strain gauge configuration is shown in Figure 2(a). The telemetry system and the strain gauges are appropriately protected against the rough environmental conditions and impacts with external objects.
