We present the design of arterial compliance probes for measurement of local pulse wave velocity (PWV). Two designs of compliance probe are discussed, viz (a) a magnetic plethysmograph (MPG) based probe, and (b) a photoplethysmograph (PPG) based probe. The ability of the local PWV probes to consistently capture carotid blood pulse waves is verified by in-vivo trials on few volunteers. The probes could reliably perform repeatable measurements of local PWV from carotid artery along small artery sections less than 20 mm. Further, correlation between the measured values of local PWV using probes and various measures of blood pressure (BP) was also investigated. The study indicates that such arterial compliance probes have strong potential in cuff less BP monitoring.

This concept is known as Microwave Power transmission (MPT). We also discussed the technological developments in Wireless Power Transmission (WPT). The advantages, disadvantages, biological impacts and applications of WPT are also presented. In recent years, the notion of transfer of power using wireless techniques has attracted many researchers. Transfer of power by wireless means has been recently demonstrated in the Massachusetts Institute of Technology (MIT). This system operates at 9.9 MHz. In this paper, we have discussed the design of a simple and cost-effective system which can enable transmission of power over short distances. We have employed the H – Bridge Inverter configuration to convert DC power to high frequency (100 kHz) which is then radiated with the help of a suitable loop antenna. It is observed that this system can also be used as a induction heating unit. In this form it can be used to replace conventional convection heating based electric stoves.

More road accidents keep on occurring due to the drivers reckless driving and the habit of travelling speeds above permitted limits. It’s very difficult task to monitor lacks of vehicle across the country at a time. The government had tried and brought in new technical solutions to solve this problem. But the existing systems have many loopholes and a higher probability of error. So we have tried here to make a new system which is capable of monitoring all the vehicles in an error freeway which is very easy to use. Here we use a system which uses the potential of RFIDs to solve the problems in traffic monitoring. Together with the immense power of internet our RFID based intelligent traffic monitoring system is easy to monitor, can be used to monitor lacks of vehicles at a time and acts at ultra-high speed. We can also get the information on reckless driving of the driver even if he is not near a receptor at the time of over speeding.

The sensors utilize a Hall effect magnetic field sensor to capture the blood pulse waveform. A strap based design is performed to enable reliable capture of large number of cardiac cycles with relative ease. The ability of the transducer to consistently detect the blood pulse is verified by in-vivo trials on few volunteers. A duality of such transducers is utilized to capture the local PWV at the carotid artery. The pulse transit time (PTT) between the two detected pulse waveforms, measured along a small section of the carotid artery, was evaluated using automated algorithms to ensure consistency of measurements. The correlation between the measured values of local PWV and BP was also investigated. The developed transducers provide a reliable, easy modality for detecting pulse waveform on superficial arteries. Such transducers, used for measurement of local PWV, could potentially be utilized for cuffless, continuous evaluation of BP at various superficial arterial sites.
