Every year 7 million people die worldwide as a result of exposure to polluted air. With up to 5 times more air pollution being found indoors than outdoors, indoor air quality is currently one of the top five environmental risks to public health as it can impact people’s energy efficiency, performance, well-being, and health. One aspect that negatively affects indoor air quality is carbon dioxide (CO2)...

When we think of “air quality”, we tend to think of air pollution in the regions surrounding our homes. We rely on measures such as the Air Quality Index to let us know when airborne pollutants in our towns or cities reach levels that may cause or exacerbate health issues. When summer humidity brings an increased risk for asthma sufferers or when dangerous smog accumulates in cities, the message is simple: to protect your health, stay indoors.

How will we be living in the future? This is a question that humanity has always yearned and worked to answer. Finding out the answer, surprisingly, is not limited to time travel. Humanity has a tendency to shape its own future by pushing forward certain developments, and now, at the forefront of this decade’s developments are autonomous deliveries, smart home devices like thermostats that control heating, cooling and ventilation based on user preferences, refrigerators that automatically send out orders when food is running low, and smart speakers that communicate with their owners...

Inhalers are among the most commonly used devices for treating respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD). With each inhalation through the inhaler, the device delivers a specific amount of medication to the lungs. However, when it comes to proper inhaler use, misuse is the norm...

Particulate Matter, abbreviated as ‘PM’, is a mixture of airborne solid particles and liquid droplets that can be inhaled and may cause serious health problems. PM includes particles with different characteristics – i.e. shape, optical properties, size and composition ¬– but it is most commonly divided into sub-categories based on the particle size information. Different PM categories are usually reported under the ...

Modern medicine has been able to drastically improve the quality of life of the global population. Diseases such as polio, syphilis, tuberculosis or the plague have been almost eradicated and are successfully treatable or curable. The next milestone for modern medicine is personalized medicine. This novel discipline does not target the broad population, but focuses on the individual for the diagnosis and beyond ...

In medical diagnostics, the trend towards near-patient lab diagnostics (point-of-care testing, or POCT) continues apace. The idea is that testing should take place as promptly as possible and ideally directly at the patient’s bedside. For more complex examinations, precise microfluidic systems are required ...
