Extracting Electric Power From Human Body For Supplying Neural Recording System

Abstract

-A powerful approach to the characterization of cellular electrical activity is electrical recording from cells or living tissues. The human central and / or peripheral nervous system has been a subject of study and fascination of the neuroscience and biomedical engineering communities for many decades. In this paper, we propose a new approach to feed implantable neural recording system, which based on extracting electrical power from human tissue warmth in order to supply a biomedical neural recording system. The major issue to overcome, in the design of a system that is aimed at being implant into the human body, is having a low power consumption, low noise circuit and small dimension to minimize tissue damage.

Design of an adaptive medium access control protocol for wireless body area networks with heterogeneous sensors

“…The physical radio model is similar to the one used in SMA-WiBAN, 23 in which the specifications were taken from previous studies. [24][25][26][27][28] The most important parameters chosen in our model are as follows: data rate = 1024 Kbps; receiver sensitivity = 287 dBm; transmission power = 210 dBm; transition time between receiving RX and transmitting TX = 20 ms; slot allocation length = 10 ms; number of allocation slots in a beacon period = 32; five sensors and one coordinator, with their corresponding specifications, as shown in Table 3.…”

“…The y-axis represents the percentage of packets that fall in the respective delay interval. For each delay interval, the performance is shown for five (contention, scheduled) combinations, namely: (1, 10), (7,8), (13,6), (19,4), and (25,2).…”

Design of Vibration-Based Miniature Generator Using Piezoelectric Bender

“…The difference among temperatures makes the thermoelectric device to generate the electric power. It is proposed that power extracted from the human tissue warmth is supplied to a wireless neural recording system implanted in human body [11]. However, it is not suitable for the environment of vibration.…”

Designing and Implementation of Liquid Electronic Circuits Using Implantable Material-First Step towards Human-circuit Interface

“…[9] . Some of the scientists (2009) have done experiments on human live cells.After the successful theoretical study, they proposed a novel human implantable neural recording system which can extract the power from live human cell and supply the same power for the biomedical neural recording system [10] .…”
