Sonavation’s ultrasound biometric technology has been architected to deliver advanced security and ease of integration into mobile and IoT devices.
Acoustic Impediography
• Sensor directly measures the finger tip structure
• Fingerprint valleys provide low damping of pillar
• Fingerprint ridges provide high damping to the pillar
• Image resolution is equal to pillar density
• A unique singular acoustic fingerprint signature
High Resolution Fingerprint Matching Using Level 3 Features: (Ridges, Valleys, and Pores).
• High resolution fingerprint matching
• Detects Ridges, Valleys, Pores
• Spoof resistant
• Ultra low power
• Low cost
Our Sensor Is Developed Using
1 – 3 Advanced Composites
• Small pitch size ~50 um
• Higher mechanical strength for compression and tensile
• Insensitive to shock and vibration
• Image resolution and sensitivity can be tuned
• Lower cost versus silicon wafer
• Trade secret protected manufacturing process
• Designed and manufactured in the USA
Paired With An ASIC and Programmed
