Mobile phone applications: Detect allergens before you eat
Ozcan’s group at UCLA has created another device called the iTube. This is an assay device that measures the concentrations of specific allergens in food. The cell phone serves as the readout interface to a very intricate biochemistry that is done with a small sample of the food. Typically, food allergen testing requires the services…

Mobile phone applications: Fluorescent microscopy
Ozcan’s group at UCLA has been innovating with mobile phones for many years before the field had developed as much as it is today. This lab had come up with fluorescent microscope on a cell phone for detection of pathogens in 2008. They also developed LUCAS which was the Lenseless Ultrawide-field Cell monitoring array which…

Mobile applications: Microscope for pictures of skin or ear.
Need: A device that can take a picture of skin or ear that is easy to use and operate. Cellscope intends to make add-on lenses and software that will enable patients to take pictures of their ear, transmit to the doctor for quick diagnosis. The device was conceived at Dan Fletcher’s Lab in Berkeley (http://fletchlab.berkeley.edu/)…

Mobile applications: Eye test using mobile phone (NETRA)
Some things are simple just by using current technology and combining them in interesting ways. Problem statement: It is difficult to get an eye test in remote parts of the world where the doctors do not visit or cannot visit. Alternatively, an eye test requires complex instrumentation and is expensive that the Doctor even if…

Optical Accelerometers
Accelerometers are microelectronic devices as discussed in this blog earlier that are commonly used in mobile phones, air bags and cameras. These are mechanical devices that measure piezoelectric, piezoresistive or capacitative based sensors that measure movement of a small weight. However, there is new technology available that uses lasers to measure movement. These are called…

Accelerometers in phones – Which chip in my phone?
Many of the phone today, have accelerometer chips and they all seem to be sourced from a handful of manufacturers. Cell phone manufacturers also change their favorite chip and since each of them have slightly different characteristics, it is likely that they will give different results. Here is a list of Cell phone manufacturers, their…

Accelerometers in phones – What is it?
There are different kinds of accelerometers in phones. They seem to vary in characteristics in different phones. The accelerometer can be thought up as a device that measures gravity. The way to imagine an accelerometer is that of a ball hung on a spring that is attached to a solid surface (like the phone). As…

Aetna mobile health initiatives
Aetna CEO, Mark Bertolini spoke at the 2012 4th annual mHealth summit and summarized his companies outlook to mHealth. He made some very interesting points. First of all, he recognized that the health system was expensive and that it was useful for a company like Aetna to participate in mobile health initiatives to reduce cost.…

Mobile devices with emotion
We think of mobile devices mainly as information exchange devices. The provide exchange of thoughts through words and also from looking up information on the internet they can provide sources of information, data and even ideas. The mobile devices of today are equipped with a lot of sensors: accelerometers, gravity, light, sound and even pressure.…

Developing mobile applications: What does it take to develop mobile applications?
The cost: Each application varies and the cost obviously is different. However, for a reasonably complex application it has been estimated that it cost about $50-$150K. Users expect a lot from their applications so most applications are probably in the higher range. The link below has some very useful discussion on the topic but it…
