In recent years, engineers and material scientists have introduced increasingly flexible electronics that could be used to create new wearable devices, such as smart watches, biosensors and health-monitoring technologies. To be safely worn by humans for prolonged periods of time, these electronics should also be permeable (i.e., letting air and humidity pass through) and bio-compatible (i.e., not harmful to the human body).
