Octopus Sucker Inspired Viscous Wearable Sensor And Underwater Sonar Sensor

- May 27, 2019-

Wearable electronic products attached to the skin are an emerging trend in health sensor technology, but existing materials have different limitations. Scientists are inspired by the octopus suction cups that are flexible and can be used in wet and dry environments. A viscous biosensor of graphene material that monitors a variety of human activities, from heart rate to stride.

Inspired by wearable sensors

According to a study published in the American Chemical Society (ACS) journal, wearable sensors, ultrasonic sensor, underwater sonar sensor, must be flexible and fully adhered to wet or dry skin to be truly effective, while also taking care of wearing comfort. Sex, so sensing the material on which the compound depends is critical. However, the materials used today have their own limitations. For example, the widely used woven yarns cannot be adhered to the skin. Typical yarns and threads are susceptible to the moist environment, and the adhesive may not stick in the water.

To develop more practical materials, scientists have added graphene and polydimethylsiloxane (PDMS) film coatings to fabrics and etched tiny octopus-like patterns on the film, finding that such sensors can be applied. Normally detect various pressures and movements in a humid and dry environment. Scientists say the device can monitor a range of human activities, including ECG signals, pulse and speech patterns, and have potential uses in medical applications.
