Tiny, Flexible Sensor Gauges
Abstract
Miniature, flexible, and transparent droplet-based pressure sensing device.
Full Description
There is a need for an accurate, flexible, and fast pressure sensor for miniaturized applications. Utilizing the ultrasensitive and elastic properties of a liquid droplet is an attractive option, but presents its own challenges in controlling the droplet, returning it to its original shape, and overcoming evaporation problems. Researchers at the University of California, Davis have integrated a droplet into a flexible polymer structure, to create a miniature, transparent and flexible pressure sensor that is insensitive to evaporation.
Applications
The miniature sensor has a multitude of applications including measurement of blood pressure, intraocular pressure monitoring, tactile sensing, and microfluidic sensing.
Features/Benefits
- Mechanical flexibility
- Fast response time
- Optically transparent
- Ultrahigh sensitivity and resolution
- Simple fabrication
- Insensitive to evaporation and thermal noise
