Ultrasonic Proximity Sensors are non-contact sensors that generate inaudible ultrasonic sound waves that detect the target from timing of the received sound waves. There are two basic types of Ultrasonic Sensors including Through Beam (Opposed, Thru-Beam, Sender-Receiver) and Diffused (Proximity, Prox) modes that are used in industrial. We report on the long-term stability of micromachined silicon membrane resonators for ultrasound based object detection and proximity sensing. The proximity sensor system measures distances up to 10 cm using either a phase or an acoustic Fabry-Perot measurement method. In these applications the transducer elements are continuously excited at their fundamental resonance using the.

The goal of this project is to design and fabricate a novel ultrasonic fingerprint sensor based on high-frequency Piezoelectric Micromachined Ultrasonic Transducers (PMUTs).
Present fingerprint sensors in portable devices, such as capacitive fingerprint sensors, have failed to gain wide acceptance due to their susceptibility to contamination.

Micromachined Ultrasound-Based Proximity Sensors will be of interest to MEMS researchers as well as those involved in solid-state sensor development. Motion Sensors • Monitor location of various parts in a system – absolute/relative position – angular/relative displacement – proximity – acceleration • Principle of operation – Magnetic, resistive, capacitance, inductive, eddy current, etc.
Primary Secondary LVDT Displacement Sensor. The polar angle θ can finally be found from: (5) θ = c o s-1 1 cot β n s 2 + cot β w e 2 + 1. Eq.s and can be used to find the direction to a light source in 3D space. Two such directional sensors provide two angular values to a source from different locations on the surface.
These angles can be used to triangulate the height of the light source from the surface. A micro-fluxgate sensor based on thin solenoid coils with integrated readout CMOS circuitry has been reported by Kawahito et al. Miniaturization of the fluxgate sensor utilizing Si process technology is driven by advantages such as the small size, light weight, low cost, higher resolution and integration of the supporting electronic circuitry.
