Researchers at Penn State University in the United States have developed a wireless wearable sensor, according to

The wireless sensor can transmit data to an NFC enabled device. It can also be used to take biometric measurements by printing on a person’s skin.

The sensors have the capability of continuously and precisely measuring humidity, heart performance signals, temperature, and blood oxygen levels.

The sensors can be printed into the skin. This will be done using a process developed by the Penn State University researchers that bonds the metallic components of a sensor at room temperature. This is contrary to the high temperatures required by other sintering and bonding processes.

The printing technique uses polyvinyl alcohol paste and calcium bicarbonate. These two are the constituents of the room temperature sintering aid layer.

This layer allows for an ultra-thin layer of metal patterns that can fold and bend. It also decreases the roughness of the printing surface.

After printing, an air blower is then used to remove the water used as a solvent.

The sensors can be removed once they are no longer needed with warm water. Also, the removal process does not damage the skin.

The sensors can be used in diagnostic testing, healthcare monitoring, and detection of diseases. They can also be used to monitor environmental conditions.

We’ve reported that Xiaomi now allows its smart home device owners to monitor and control the lighting, entertainment, security systems by tapping an NFC sticker with their smartphones.
