The 21st century has seen amazing advances in technology; one of the most amazing instances is biosensing. This technology didn't just happen overnight, it took decades of research and development.
Electronic engineering is constantly evolving. As new technologies are developed, so are new applications for those technologies. One such application is biosensing.
Biosensing technology is the measure of a biological response to stimuli using electronic devices. This can be done with impedance, capacitance, or field-effect biosensors.
This article will explore the history of biosensing and how custom electronic engineering made it possible.
What Is Biosensing Technology?
Biosensing is a fascinating field of technology that can detect and measure biological parameters such as pH, temperature, humidity, pressure, glucose levels, or even oxygen levels in the atmosphere. It's being used for medical diagnostics, food safety, environmental monitoring, and security purposes but most importantly it helps us better understand ourselves by detecting changes occurring naturally within our bodies.
Business owners, electronic producers, and manufacturers have all become increasingly interested in biosensing technology. This is because biosensing can be used to create more efficient products with a longer lifespan. It also helps to improve the safety of products.
What is biosensing technology?
Biosensors are used in a variety of applications to detect and measure biological or chemical substances. This can be done using electrical, optical, and mechanical sensors that create more efficient products with longer lifespans while also improving safety by eliminating the need for costly laboratory testing. When food manufacturers use them, it ensures customers will get fresher ingredients without any worries about what's inside!
As business owners, electronic producers, and manufacturers become increasingly aware of its potential, we will likely see more and more biosensor-equipped products on the market.
Benefits of Biosensing
Biosensing technology has wide-ranging applications in the fields of healthcare, environmental monitoring, food safety, and homeland security.
Here, we will focus on three key areas in which biosensing devices are having a major impact.
1-Healthcares
Numerous handheld biosensing devices are currently available that can be used for point-of-care (POC) testing. A POC test is defined as "a diagnostic test performed at or near the site of patient care to obtain immediate results that will guide clinical decision-making.
The most common POC tests are those that measure blood glucose levels (for diabetes management), cholesterol levels (for cardiovascular risk assessment), and pregnancy hormone levels (for pregnancy detection). Other POC tests that are currently being developed include those for the rapid detection of infectious diseases such as influenza, Ebola, and HIV.
2-Environmental Monitoring
Biosensors can be employed for environmental monitoring in some ways. For example, they can be used to detect water contamination, air pollution, and soil contamination. They can also be used to monitor greenhouse gasses, such as carbon dioxide and methane.
3-Food Safety
Foodborne illnesses are a major problem worldwide, causing an estimated 420,000 deaths each year. Biosensors offer a rapid and accurate way to detect foodborne pathogens, such as Listeria monocytogenes and Salmonella bacteria. Pathogen detection biosensors can be used in both the food processing environment and by consumers at home.
How Custom Electronic Engineering Made Biosensing Possible ?
Some of the key custom electronic engineering developments that have made biosensing possible include miniaturization techniques such as microelectronics and nanotechnology; advances in material science; improved understanding of cell physiology and methods for immobilizing biomolecules onto surfaces.
Think, for example, of a glucose sensor implanted beneath the skin that monitors blood sugar levels in real-time and sends that information wirelessly to a nearby smartphone or tablet. That's one example of a biosensing device that has been made possible by custom electronic engineering.
Let's take a closer look at how custom electronic engineering has made biosensing possible and explore some of the applications of biosensing that are being manufactured today.
The miniaturization of electronics has been a major step in making biosensing possible. Consider the implantable glucose sensor. This device relies on a tiny amount of electronics embedded in a flexible substrate. This is only possible because of the advances that have been made in custom electronic engineering.
Traditional electronics are rigid and brittle, making them impractical for biosensing applications. But custom electronic engineering has made it possible to create flexible electronics that can be easily integrated into living systems.
There are countless potential applications for biosensing devices, but here are just a few examples of what is being manufactured today:
1- Implantable medical devices like pacemakers and insulin pumps
2- In-ear hearing aids
3- Smart contact lenses
4- Wearable fitness trackers
5- Environmental sensors
Potential Applications of Biosensing Technology
Let's have a closer look at Biosensing Technology applications :
1- Healthcare
Biosensors can be used to monitor various aspects of a person's health in real time. For example, to measure heart rate, respiration rate, body temperature, blood pressure, and blood sugar levels.
2- Food safety
Biosensors can be used to detect foodborne pathogens such as E. coli and salmonella. This information ensures that food is safe to consume and prevents large-scale outbreaks of food poisoning.
3- Environmental monitoring
Biosensors can be used to monitor environmental factors such as air quality, water quality, and noise levels. This information improves public health and safety by alerting people to hazardous conditions in their environment.
4- National security
This technology also can detect bioweapons such as anthrax and smallpox. This information protects citizens from terrorist attacks or the accidental release of these agents into the environment.
5- Forensic science
Biosensors can be used to identify individuals based on their unique biometric signatures such as DNA, fingerprints, or iris patterns. This information can be used in criminal investigations to identify suspects or victims.
6- Consumer products
Biosensors can be integrated into consumer products such as cell phones, fitness trackers, and smartwatches. This information improves the user's experience by providing them with personalized data about their health or environment.
7- Manufacturing
Biosensors can be used to monitor industrial processes for toxic chemicals or pathogens. It helps to ensure that products are safe for human consumption or prevent worker exposure to hazardous materials.
8- Agriculture
Biosensors can be used to monitor crops for pests or diseases. It helps to improve crop yields by allowing farmers to take corrective action before plants are damaged.
Conclusion
Custom electronic engineering has revolutionized biosensing technology. The development and implementation of new, flexible devices have made it possible for scientists to study living systems with extreme precision than was previously imaginable—all without sacrificing safety or portability!
Biosensing devices have been around for some time now, but they're just getting more popular because of their many potential application—from medical equipment like insulin pumps and pacemakers to electronic hearing aids which help people hear better by picking up on those sound waves that are closer than the others, or also smart contact lenses so you don't need glasses when outdoors at night or wearing dark clothes.
