We live in an age of ever-advancing technology that pushes the boundaries of biology and healthcare. No department should get left behind. Including the chaotic rush of A&E.

Triage is a system through which provision of medical treatment is allocated to maximise the number of survivors in a situation where demand for treatment is higher than the hospital is able to provide (1). In practice, this means that patients are treated according to the severity and urgency of their injury or illness as opposed to a first come, first served-based system. Triage initially began as a method of maximising survivors of battlefield injuries, and as such is historically a largely trauma-based system. Changing healthcare landscapes and demands have prompted triage to evolve into an integrated multi-stage system in which all kinds of injuries and illnesses must be accommodated and sorted to allow urgent cases to be treated as quickly as possible (2).

Food deemed to be unsafe can contribute to a variety of diseases, from gastrointestinal issues to cancer. Food safety is a global public health concern, heavily impacting both developed and developing countries, it is vital to minimise contamination and associated outbreaks of disease. Therefore, the monitoring of food safety and the environment in which it is produced is crucial in maintaining a safe food production and supply process (1, 2).

Tracking one’s health and wellbeing has never been as easy as it is in the 21^st century. In addition to the wealth of health-related information easily available on the internet, the evolution of portable and wearable technology has made it possible to track aspects of one’s wellbeing on the go. Sleep quality, stress levels, and heart rate are only some of the health indicators that widely available smart devices allow users to assess. Wearable wellbeing diagnostics are in high demand and the industry is experiencing rapid growth: the number of connected wearable devices worldwide more than doubled between 2016 and 2019 and is expected to surpass 1 billion in 2022 (1), while the market for wearable health sensors is predicted to grow by 10.5% between 2021 and 2026 (2).
