Advancements in biomedical engineering have led to the development of a variety of ingestible sensors and moving towards insertable sensors. These are miniaturized, wireless devices capable of real-time biochemical monitoring within the body. These sensors hold significant promise for non-invasive, longitudinal health monitoring, particularly in gastrointestinal health in whole population and gynecological health in women.
Gas and chemical sensing in the gastrointestinal (GI) tract plays a critical role in diagnosing and continuously monitoring conditions such as irritable bowel syndrome, inflammatory bowel disease, and food intolerances. Traditional diagnostic techniques for measuring and pinpointing the location of gases and chemicals typically involve invasive, hospital-based procedures.
According to the United Nations Environment Programme report on the Food Waste Index,1 approximately 18% of the world's food production is wasted throughout the food chain. Furthermore, food waste is responsible for around 10% of global greenhouse gas emissions, posing a universal challenge to both escalating global hunger and climate change. In this context, technologies that continuously assess the condition of food are necessary to prevent spoilage and subsequent waste.
