LD20 Liquid Flow Sensor Is Part of Wearable Drug Delivery IoT Platform

Posted on by mixos

At this year’s MD&M West trade fair (Anaheim, United States), the sensor expert Sensirion and Quantex Arc Ltd will be presenting an innovative concept study in the field of infusion technology – Quantex’s new wearable drug delivery IoT Platform “Quantex 4C”.

Sensirion is a leading manufacturer of environmental as well as gas and liquid flow sensors. The cost-effective LD20 single-use liquid flow sensor, which has been used for this concept study, is exceptionally compact and measures flow rates in the micro and milliliter per hour range with outstanding precision and reliability thanks to the patented CMOSens® Technology. Additionally, it features sensitive failure detection mechanisms to help counteract, for example, occlusions and air-in-line. Quantex is an innovative leader in single-use disposable pump technology. The pump’s design is based on a rotary, fixed displacement principle thus is much less sensitive to variables such as line pressure, fluid viscosity and flow rate.

The new wearable drug delivery IoT platform “Quantex 4C” demonstrates an innovative approach to infusion therapies. It integrates connectivity with a modular drug delivery platform and enables continuous monitoring of the therapy with the help of a single use liquid flow sensor for safe ambulatory treatments.

Real time bidirectional flow verification at the low flow rates that are typical for the targeted application and the sensor’s compact form factor made the Sensirion LD20 single-use liquid flow sensor the ideal choice”, said Paul Pankhurst, Founder and CEO of Quantex.

The objective of the presented study is to demonstrate the possibilities of a comprehensive drug delivery system to the medical technology industry. The compactness, low power consumption and cost-effectiveness of both, sensor and pump, allow the design of a wearable device which controls and monitors the drug delivery therapy simultaneously. Such a connected drug delivery platform opens up entirely new possibilities for all involved stakeholders. While patients and clinicians benefit from an increased ease of use and confidence in the therapy, low maintenance and less training efforts; it allows healthcare and pharma companies to capture vital adherence data and simplifies patient compliance.

Disposable LD20 Flow Sensor by Sensirion

Reliable failure detection is a central requirement for next generation drug delivery devices. Ambulatory treatments and wearable applications will only be successful if patients as well as clinicians trust the reliability of those next generation devices.

Visit both companies, Sensirion (Booth 1556) and Quantex (Booth 1958), from February 5 – 7, 2019 at MD&M West in Anaheim to learn more about the concept study.

Posted on by Ayo Ayibiowu

I remember many years ago, when I was trying to acquire data with hardware especially with “Data Acquisition” devices, I was gifted a device that I must say reshaped my life – It was the NI myDAQ. The NI myDAQ was a product from National Instrument, and it allowed students to perform hands-on experimentation in or outside the lab. It was like your personal lab arsenal in your pocket, and you could turn it to most instruments you can think off.

NI myDAQ impacted the STEM Education, but those are the days of NI myDAQ. A new entry to this arena is the PSLab also called Pocket Science Lab, which I am personally impressed about and the NI myDAQ is not really a competitor of it in terms of cost, features, openness, welcomes, and many more. PSLab is an complete open source platform for STEM Education.

PB50 Detects Radiation between 1 and 5.2 microns

Posted on by mixos

LASER COMPONENTS is a world leading manufacturer of lead salt infrared detectors. From our research and production facility in Arizona we supply customers all over the world with these industrial grade thermal detectors.

These detectors work on the principle that photons incident on the polycrystalline thin film promote electrons across the bandgap increasing the conductivity of the material in turn decreasing the resistance of the substance. The polycrystalline lead selenide (PbSe) units detect radiation in the wavelength range between 1 and 5.2 microns.

The resistance of photoconductive detectors depends on the incident light. PbSe has a particularly strong inner photoelectric effect: When infrared light reaches the lead selenide detector, the resistance is reduced. The detectors can be used uncooled at a wavelength of up to 4.7 µm. At room temperature, they exhibit a detectivity D* of greater than 1010. At low temperatures, they achieve an even higher performance level; in addition, the wavelength shifts to 5.2 µm.

The devices are manufactured in standard TO style packages and have long expected lifetimes making them ideal for fit and forget applications such as gas sensing, surface inspection and flame detection. The PB50 device is a collection of TE cooled polycrystalline biased single element PbSe detectors that operate at room temperature with a 20% cut off at 4.9 microns and a maximum element size of 6 x 6 mm2.

LCDGP

Application Fields

PbSe detectors react very quickly and are thus particularly well suited for high-speed applications, such as, for example, the detection of hot spots. They are also used in medical gas analysis (CO2 measurements), emissions measurements in the industrial field and the automobile industry, and in the measurement of moisture and hydrocarbons.

ON Semi – Silicon Photomultiplier RB-Series

Posted on by mixos

ON Semi’s RB Series of red-enhanced second generation Silicon Photomultipliers (SiPM) with high responsivity at a low bias voltage.

MicroRB−Series sensors are the second release of Silicon Photo− multipliers (SiPM) from ON Semiconductor’s R-Series range. These sensors provide further sensitivity improvements in the red and NIR region of the electromagnetic spectrum. All R-Series SiPM sensors feature high responsivity, fast signal response and a low temperature coefficient of operating voltage, all achieved at a low bias voltage.

The sensor is packaged in a compact and robust MLP (molded lead frame) package that is suitable for reflow solder processes. Both the sensor and the package are designed for volume production with the product delivered on tape and reel.

SiPM sensors are an improvement over avalanche photodiodes (APD) and PIN diodes due to their high gain and single photon sensitivity. This enables the detection of low reflectivity targets at very long distance in LiDAR applications. Unlike the similarly-operated SPAD that can only detect single photons, the SiPM overcomes this limitation by incorporating a ‘microcell’ structure that allows for multi-photon detection with a high dynamic range.

It is strongly recommended that those new to SiPM sensors consult the Introduction to Silicon Photomultipliers application note.

Features

  • High gain and detection efficiency
  • From a unique ‘fast output’ terminal
  • PDE of >10 % at 905 nm
  • Single photon sensitivity
  • 1 mm sensor size, which a choice of microcell size
  • Compact and robust MLP package
  • <50 V bias voltage

Applications

  • 3D ranging & sensing
  • Medical imaging
  • Hazard & threat
  • Biophotonics & sciences
  • High energy physics
