Wearable biosensors are portable electronic devices that enable real-time monitoring and feedback to the user on various biological and physiological indicators. It has been suggested that they could revolutionise personalised healthcare and home management of patients by enabling continuous monitoring of vital signs 1,2.
Methods by which wearable biosensors can integrate sensors into the human body include smart watches, implants, clothing, tattoos, patches or rings. They can provide real-time measurement of various biological parameters, including blood pressure, heart rate, temperature, respiratory rate and activity levels 1.
More recently, wearable biosensors have been increasingly utilized during the COVID-19 pandemic to monitor vital signs that may be early or presymptomatic indicators of infection 3.
The sensors may inadvertently be observed whilst undertaking imaging investigations.
