FAQs:

Q1: What is Biomedical Instrumentation?

Basic Electronics Notes

A1: Biomedical instrumentation is the application of knowledge and technologies to solve problems related to living biological systems. It involves diagnosis, treatment and prevention of disease in human. The term “bio” is to denote something related to life.

Q2: What does Biomedical Instrumentation involves?

A2: It involves measurement of biological signals like ECG, EMG, or any electrical signals generated in the human body. To diagnose the problem and to provide treatment Biomedical Instrumentation helps physicians. Concepts of electronics and measurement techniques are needed To measure biological signals and to design a medical instrument.

Q3: What is the scope of Biomedical Instrumentation?

A3: As the medical field is emerging, the area of Biomedical Instrumentation is an expanding field. The drastic advancement of technology involved in biomedical engineering will carry on changing the job profile of biomedical engineers. It will also carry on creating new work areas. Hence, there is a need to convert the expanding range of activities for biomedical engineers into very favorable job prospects. The retirement of a substantial count and fast aging of the population of biomedical engineers is possible to result in huge job openings between the period of 2019 and 2024.

Employment of biomedical engineers is expected to grow at seven per cent from 2016 to 2026. As the aging baby-boom generation stays active and lives longer, the demand for biomedical procedures and devices is expected to increase. Several opportunities exist for students pursuing a course in biomedical sciences in India. It is a huge, happening subject with huge opportunities for management, laboratory work, education, research, and consultancy. Once you become competent in the subject, you can work in the private sector or the numerous national healthcare laboratories. Those who do not find themselves appropriate for standard hospital careers may choose for health protection agencies, or work in forensic science departments. Job profile include:

• Instrument engineer
• Bio medical engineer
• Researcher
• Installation engineer
• Maintenance engineer

Brain Wave Machine - Humans have been using light and sound to achieve altered states of consciousness for thousands of years. Primitive cultures used flickering fires and rythmic drumming to induce these altered states. Today, you can choose from a wide variety of electronic brain-wave machines which use light and/or sound to alter brain-wave activity. Brain-wave activity ranges from fully awake to deep dreamless sleep. This activity is categorized into five primary groups: Delta, Theta, Alpha, Beta, and Gamma. __ Designed by © Hack Canada

Convert your smartphone into a pedometer & tracking Device - EDN-Design Ideas 10/22/12 When you go hiking or mountain biking, or simply take a long walk around the neighborhood, you might wonder about the distance you covered or specific details, such as speed. A specialized device for such a task is an expensive idea. Now, however, the increasing penetration of smartphones in the market with built-in GPS devices makes it possible to configure a mobile phone to log or send the current readings from its sensors to a server for viewing and processing. This design idea describes a simple approach to log readings from a GPS using the Python scripting language. An advantage of Python is that an electronics engineer need not delve into the complex realm of C/C++ calls for Symbian/Android architectures to accomplish this simple task. All that is required is the installation on a phone of the Python interpreter, along with a text file containing the script. __ Circuit Design by Ali Asgher Mansoor Habiby and Abdus Sami Abdul Qayyum, Sir Syed University, Karachi, Pakistan
