Disclosed is an ultra thin optical scanning device for a portable information device, which includes an LED as a light source and totally reflects light from an object-side surface to form an image, thereby increasing a contrast ratio of the image and improving the resolution thereof. The ultra thin optical scanning device includes a light emitting device that emits light for sensing an object, an object-side surface contacting the object and totally reflecting the light emitted from the light emitting device, an image formation part collecting the light totally reflected by the object-side surface, and transmitting the light, and a light receiver part forming an image by using the light transmitted by the image formation part.

A sensor for measuring heat generated from cells, including a thermopile manufactured by surface-micromachining technology, and a microfluidic flow-channel structure for mixing cells with medium and dividing the mixture into cells and medium. Medium and cells are uniformly mixed using a micro-mixer. The mixture is separated into a medium microfluid and a cell microfluid using the Zweifach-Fung effect, after which signals measured in the two microfluids are amplified. The difference between the two signal values determines the amount of heat generated from the cells. The influence of noise caused by a change in external environment is eliminated. Convection heat dissipation caused by fluid flow is minimized. The sensor accurately measures the amount of heat generated from cells flowing in the microfluidic flow-channel. Diseases such as cancer are diagnosed using the difference between the measured amount of heat generated from cells and the standard amount of heat generated from normal cells.
