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…

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…

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/)…

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…

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…

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…
