Researchers from the University of California Davis (UCD) has developed ‘Smart’ contact lenses that measure pressure within the eye and dispense medication accordingly.
Starting with a material called polydimethylsiloxane (PDMS), researcher from UCD developed a method for placing powdered silver on the PDMS in a precise pattern, to create conductive wires.
The researchers, including Tingrui Pan and Hailin Cong, then shaped the PDMS-silver into a contact-lens shape, and showed its function as a pressure sensor.
Glaucoma, a build-up of pressure in the eye, is a leading cause of blindness worldwide. A contact lens that could continuously measure pressure within the eye and relay the data to a computer, allowing doctors to learn more about glaucoma and improve patient treatment.
The researchers plan to apply for approval to begin trials for the lenses in humans.

Researchers at the California Institute of Technology have developed a super-compact high-resolution microscope, small enough to fit on a finger tip. The ‘microscopic microscope’ operates without lenses, but has the magnifying power of a top quality optical microscope.
The new instrument combines traditional computer-chip technology with microfluidics – the channelling of flow fluid flow at incredibly small scales. An entire optofluidic chip is about the size of a quarter, although the part of the device that images objects is only size of Washington’s nose on that quarter.

A high-performance, low-power silicon nanoscale sensor is being developed by engineers from The University of Southampton’s School of Electronics and Computer Science as part of a three-year European FP7-funded NEMSIC (Nano-electro-mechanical-system-integrated-circuits) project.
Project leader Professor Hiroshi Mizuta, and his team at ECS will co-integrate single-electron transistors (SETs) and nano-electro-mechanical systems (NEMS) on a single silicon technology platform to create a small, sensitve sensor with low-power consumption.

A self-powered sensor designed to monitor progress during knee operations, has been developed by a student from The University of Southampton’s School of Electronics and Computer Science.
Serial In-vivo Transducer (SIT), developed by Fauzan Baharudin, uses thick film technology to measure tendon force during Anterior Cruciate Ligament (ACL) reconstruction. The ACL is the most commonly injured ligament and is commonly damaged by athletes.

Buses could be used as mobile sensing platforms, sending out live information that can be used to control traffic and detect road hazards, according to European researchers.
In a test, researchers with the Moryne project equipped city buses with environmental sensors and cameras, allowing the vehicles to become transmitters of measurements, warnings and live or recorded videos to anyone allowed to access the data.
The researchers developed a range of technologies for mobile sensing, data acquisition, analyses and telecommunications that could be placed in public buses as a part of a larger effort to improve road safety and traffic management.

Chemists at the University of Massachusetts Amherst, have developed complex molecules containing zinc for use in portable sensors that quickly and reliably detect the presence of plastic explosives.
Sensors containing the zinc complexes are the first devices that allow the user to identify which type of explosive is present, since each metal complex has a unique response to explosives and explosive mimics.
Commenting, Michael Knapp, an assistant professor of chemistry at the University, said: “This is a big improvement over existing sensors based on polymers, since the metal complexes can discriminate between closely related explosives compounds.
“This ability is a real advantage for airport security personnel and law enforcement officials, who need to quickly detect and identify what type of explosives they are dealing with.”

A tiny sensor that can read the data from nano-scale magnetic circuits is being developed by researchers from Sheffield and Leeds Universities.
The researchers believe that in some cases, magnetic nanotechnology devices could offer higher device density, lower power consumption, improved reliability or additional functionality, compared with more traditional silicone-based devices.
The project aims to develop a network of magnetic nanowires that can process information. The magnetic polarisation of various regions, or domains of the wire would represent the binary numbers of digital information. While this is not new, the challenge facing the team is to develop a device that can read out the magnetic data in a form compatible with modern electronics.
