Wireless telemetries design

Microelectronics of Recording, Stimulation, and Wireless Telemetry for Neuroprosthetics Design and Optimization... 

These applications, by nature, impose serious limitations on power and area in the design of neural-recording systems. Researchers have developed several kinds of neural-recording systems [23-27], and those systems are generally composed of preamplifiers to amplify the small extracellular potentials, low-pass filters to reject the high frequency noise, multiplexers, and analog-to-digital converters (ADCs) followed by the wireless telemetry circuits to transmit data out of the body. 

This book. Implantable Neural Prostheses 2 Techniques and Engineering Approaches, is part two of a two-volume sequence that describes state-of-the-art advances in techniques associated with implantable neural prosthetic devices. The techniques covered include biocompatibility and biostability, hermetic packaging, electrochemical techniques for neural stimulation applications, novel electrode materials and testing, thin-film flexible microelectrode arrays, in situ characterization of microelectrode arrays, chip-size thin-film device encapsulation, microchip-embedded capacitors and microelectronics for recording, stimulation, and wireless telemetry. The design process in the development of medical devices is also discussed. 

Due to patient s physical restrictions when connected to cables and machines, Taylor,ef fl/.,[2]had designed wireless transducers for cardiotocography via radio frequency (RF) telemetry, where there was no wire connection between the transmitter and the receiver. Thus, patients feel more confortable and at ease to move. There are also many other existing researches regarding wireless transmission of ECG signals, and the transmission is always to a laptop or a personal computer (PC)[3-4].
