While piezoelectric haptic solutions are found in many applications, they are often large and heavy, thus shaking the entire device. KEMET’s new piezoelectric polymer film haptic actuators are thin (150 µm), flexible and conformable devices made from a proprietary, patent-protected paper-thin material, an electro-active polymer film, that enables piezoelectric effects to mimic the sense of […]

Undersea optical-fiber cables do double-duty as seismic sensors, Part 2: Application
A research team has devised and tested a scheme based on advanced optical-physics principles, which uses active submarine optical-fiber data cables also to sense ocean-floor earthquakes and ocean-surface swells. The previous part of this article established the context for “piggybacking” seismic-sensing capabilities onto an existing undersea fiber-optic cable. This part looks in more detail at […]
Undersea optical-fiber cables do double-duty as seismic sensors, Part 1: Context
A research team has devised and tested a scheme based on advanced optical-physics principles which uses active submarine optical-fiber data cables to also sense ocean-floor earthquakes and ocean-surface swells. Sensing of physical parameters such as temperature, pressure, force, and velocity often brings a “split personality” analysis. On one hand, getting a reading of the basic […]
Non-contact reflective object sensor targets industrial automation applications
TT Electronics announced its new OPB735 series Reflective Object Sensors for the most challenging industrial automation and safety applications. This reflective sensor features hermetically sealed components offering designers a wide operating temperature range of -55°C to 100°C to suit almost any factory setting. Designed to produce extremely low cross-talk or noise signals, this product provides users with reliable and […]
LZ-19 Series LVIT linear position sensor
The LZ-19 Series of LVIT (Linear Variable Inductance Transducer) position sensors are contactless devices designed for use in factory automation or assembly machinery applications where space is a premium, as well as for external mounting on pneumatic cylinders to sense rod position. The LVIT is offered in nominal full scale ranges from 2.5 to 750 […]
Signal conditioner handles digital/analog comm for AC-LVDTs, RVDT, or LVRT half-bridge sensors
The NewTek NTC-6000 Qwik-Cal LVDT Signal Conditioner completes the measurement system for AC-operated LVDTs by providing the excitation and digital output required by many of today’s laboratory, industrial automation, and process control applications. Without internal electronics, AC-LVDTs can operate in extreme environments but require the NTC-6000 Signal Conditioner to convert position feedback into readable output […]
Hall effects sensor optimized for low-field environments, normal ambient temps
Paragraf announces a new graphene Hall Effect sensor ideally suited to battery applications, such as the electric vehicle (EV) sector. The graphene GHS01AT Hall Effect sensor is optimized for use in relatively low field environments and normal ambient temperatures. Bringing the magnetic field measurement resolution towards that of more complex magnetic sensors, yet with the […]
What is the difference between a thermal IR sensor and a quantum IR sensor?
Infrared radiation (IR) can be detected by thermal IR and quantum IR sensors. A thermal IR sensor uses infrared energy as heat for detection and its sensitivity is independent of wavelengths. Therefore, it can detect objects in the near IR, mid IR, and far IR bands. The non-contact detectors do not require cooling after exposure […]
Calibrated and ISO 17025-certified sensors for drugs and perishable goods transportation
Sensirion has announced its new calibrated and ISO 17025-certified humidity and temperature sensors. These sensors enable customers to achieve cost-efficient GDP-compliant supply chain monitoring of drugs, vaccines, and perishable goods. Highly regulated products, such as pharmaceutical or perishable goods, typically require special handling along their distribution chain to comply with several directives. Manufacturers are obligated […]
