Fingerprint Sensors Market - Global Industry Analysis and Opportunity Assessment 2014 - 2020

Fingerprint sensor is a device used to scan and capture an image (digital) of fingerprint pattern. This captured digital image is known as live scan. Live scan is processed digitally to create collection of extracted features (biometric template) used for matching purpose. Fingerprint verification systems consist of different modules including fingerprint sensing element, preprocessing and feature extraction module and matching module among others. The growing market of small-size and low-cost acquisition devices are allowing the implementation of fingerprint sensor in a wide range of applications such as physical access, electronic commerce and PC log in among others.

Different types of fingerprint sensors include optical sensors, ultrasonic sensors and capacitive sensors. Optical fingerprint sensor is an essential component of a digital camera. Optical fingerprint sensor captures image of the fingerprint with help of visible light. The top layer of sensor is called as the touch surface used for placement of finger. Light-emitting phosphor layer is present below touch surface which illuminates surface of the finger. Ultrasonic sensors use principle of medical ultrasonography to create images of the fingerprint. These sensors employ high frequency sound waves to penetrate epidermal layer of skin of finger. Capacitance sensors employ principles related with capacitance to create fingerprint images. There are two type capacitive sensors available such as passive capacitance sensor and active capacitance sensors. Semiconductor fingerprint recognition sensor captures fingerprint images by reading changes in electric charge according to the pressure. The sensor screen is basically a thin film. They can also use an electromagnetic field or thermal impact of the finger on the sensor. They may use ultrasonic waves to convert signals into digital images. LE...
