Silver nanowires follow the skeleton pattern on each leaf, allowing for flexible application and use

Spotted: One of the main hazards of thermotherapy patches is their propensity to cause burns. Whether on older people who are less sensitive to the heat or on people who fall asleep while using their pad, traditional materials make it difficult to easily assess the activity of the treatment.

A team of researchers from Finland’s Tampere University of Applied Sciences have created a sustainable, transparent solution. The new thermotherapy patches use plant leaves as the base for silver nanowires. The nanowires follow the skeleton design of the leaf and are then encased in flexible, see-through and biodegradable tape. Wearers can monitor their body’s reaction to the heat, thereby reducing the risk of burning their skin.

The placement of the wires on the leaf vein pattern makes the patches flexible and highly effective at transferring heat. The flexibility allows wearers to move while receiving treatment, and the rapid heat transfer reduces the time required to use the patch.

Useful in treatment for conditions including arthritis and in certain types of physical therapy, the heat patches are also likely to prove beneficial to other industries, from wearables and sensors to industrial manufacturing.
