A multifunctional sensor that responds to all – static/quasi-static or dynamic temperature force is reported. The based on a ferroelectric poly(vinylidene fluoride trifluoroethylene) (P(VDF-TrFE)) capacitor connected the gate of organic field-effect transistor (OFET). Both, P(VDF-TrFE) capacitance and output voltage P(VDF-TrFE)/OFET exhibit logarithmic response static compressive force, leading higher sensitivity for small forces. In addition, both linear dependence static/constant...

In this paper, an analysis of the use wavelength and time division multiplexing techniques for quasi-distributed measurement in uniform fiber Bragg gratings is presented.To date, publications have concentrated on determination maximum number one optical using multiplexing.In these will be extended to determine spectral width terms light emitting diode, gratings, ranges individual sensors, guard band between two adjacent gratings.For multiplexing, a description power conditions are given.In...

Knowledge of an amputees' residual limb skin temperature is considered to be particular importance as indicator tissue health. Temperature within the prosthetic socket typically varies over range 25 °C 35 and this warm, confined environment causes sweating which creates favourable conditions for both growth bacteria increased risk breakdown. With in mind a wearable sensor real-time measurement variations at socket/liner interface under development proof concept prototype presented. The...

During track maintenance operations, the early detection of oncoming rail vehicles is critical for safety personnel. In addition, system should be simple to install at trackside by minimally qualified Fibre optic based sensor systems have inherent advantages being passive, unaffected radio frequency interference (RFI) and suffering very low signal attenuation. Such a therefore represents good alternative conventional approaches such as ultrasonic systems. The proposed consists one or more...

Today interferometric sensors are among the most accurate available thanks to their inherent high sensitivity. These highly versatile may be used measure phenomena such as temperature, strain, fluid level, flow, vibration, stress, etc. This article concentrates on composition of fiber-optic interferometers, in particular Mach-Zehnder type. The type is composed two arms, one for measurement and a second serving reference. When light enters interferometer, ideally phase shifted only arm while...

In light of the rapidly increasing demand for ultra-high speed data transmission, centres are under pressure to provide ever transmission through their networks and at same time improve quality handling in terms reduced latency, increased scalability improved channel users.However as rates increase, present electronic switching technology using current centre architecture is becoming increasingly difficult scale despite improvements management.In this paper tremendous bandwidth potential...

Monitoring the health of a residual limb in prosthesis is key to detect early signs tissue injury, and could improve patient quality life. However, monitoring at skin level induce possible discomfort irritation, making susceptible for breakdown. The use non-invasive sensor technologies within flexible liner prosthetic device can alleviate these issues. rehabilitation lower wearers be greatly improved by reliable continuous system that alert both user authority warning development damage. In...

In light of rapidly increasing demand for ultra-high speed data transmission, centres are under pressure to provide ever transmission through their networks and at the same time improve quality handling in terms reduced latency, increased scalability improved channel users. However as rates increase, present electronic switching technology using current centre architecture is becoming increasingly difficult scale despite management. this paper issues will be discussed alternative optical...

Recent years have seen a rapid growth in the development of e-health systems for continuous remote patient monitoring physiological data such as temperature, heart rate (HR), Blood pressure (BP), oxygenation (SpO2), respiration and glucose levels. The roll-out schemes show promise delivering improvements care while at same time reducing both demand resources financial burden on healthcare systems. These wearable are used to monitor, log transmit central health authority. Depending patient,...

Recent years have seen a rapid growth in demand for ultra high speed data transmission with end users expecting fast, bandwidth network access. With this demand, centres are under pressure to provide ever increasing rates through their networks and at the same time improve quality of handling terms reduced latency, increased scalability improved channel users. However as increase, present technology based on well-established CMOS is becoming increasingly difficult scale consequently...

Health services worldwide are seeking ways to improve patient care for amputees suffering from diabetes, and at the same time reduce costs. The monitoring of residual limb temperature, interface pressure gait can be a useful indicator tissue viability in lower especially predict occurrence ulcers. This is further exacerbated by elevated temperatures humid micro environment within prosthesis which encourages growth bacteria skin breakdown. Wearable systems prosthetic users have designed such...
