Digital Electronic Stethoscopes

The Heart, Liver and Kidney form a Vital Organ Tripod, on which rests the most Important Organ... Think about it......You are Thinking with it. Rack your Grey Matter with your copy of the Gray's Anatomy; to figure this Puzzle within.Digital Electronic Stethoscopes

Any of these three Legs, of this Tripod, Can be affected by wrong eating and living habits. After a certain age, you have to only Eat what you can burn, The rest is Poison. An electrician knows, If an Equipment is rated for for 12-Volts 3-Amps; He has to use within its Limits. An Electronics Engineer knows that he should never go near the "Absolute Maximum ratings".

Study more about the Vital Organ called Heart, by building an Electronic Stethoscope. See the Block Diagram (SBD) - Digital Stethoscope - TI.com. The sounds are very faint and a low frequency. It is a Bionic Challenge to acquire and amplify these small signals. Learn more about these concepts here ...

The SS30L Electronic Stethoscope will allow you to record and listen to heart sounds and Korotkoff sounds.

Here is a another Semiconductor Application from Maxim-IC Digital Stethoscope.

Mass Spectrometry and Portable Microbe Detector

Human Beings are helped or hampered by many types of Microbes. From the Sub-Microbe virus to animal like Bacterium and plant like Fungi.

An Affordable Portable Electronic Microbe Detector using Mass Spectrometry; may be very useful for Small HealthCare Centers and Homes. If a Person Breathes into an adapter in the instrument, it should show a simple analysis of the Air Microbe Levels. It can also be used for CleanRoom Air Purity Indication.

This is just an idea for an urgent need, this may prevent spread of flu to escalate into an epidemic; due to early detection of microbe, at the root, in every home.

Here are some Mass Spectrometry Resources that students can study and attempt to research to Develop a cost-effective consumer flu-detection device.

Products for portable ECG designs - Analog

"ADI microcontroller and integrated amplifier technologies support ultra low power, small size, and AAMI-EC13 performance level requirements for portable ECG designs."

AD8235: 40µA Micropower Instrumentation Amplifier in WLCSP Package

The AD8235 is the industry's smallest, lowest power instrumentation amplifier. It has rail to rail inputs and outputs and can operate on voltages as low as 1.8V.

AD8235: 40µA Micropower Instrumentation Amplifier in WLCSP Package

Another device of interest - 128 Channel, 24-bit Current-to-Digital ADC for High Slice Count CT Scanners. The ADAS1128 lowers CT system cost and enables enhanced imaging using the industry's highest level of channel integration and speed.

ADAS1000: Low Power, 5-Electrode ECG AFE

Some Features

  • Biopotential signals in; digitized signals out
  • 5 acquisition (ECG) channels + 1 driven lead
  • Parallel ICs for up to 10+ Electrode measurements
  • Internal Pace Detection Algorithm on 3 leads
