While discrimination based on skin color is against the law in the U.S., changes in skin color provide important information in healthcare regarding disease progression or treatment response, so accurately measuring and distinguishing skin color is essential. Skin color is also a predictor of skin cancer risk. Also, accurately measuring and matching skin color is […]

How does skin color impact biosensors?
To determine blood oxygen (arterial blood oxygen saturation (SpO2)) and pulse rate, many biosensors use the reflectance of red and infrared (and sometimes green) light. Based on photoplethysmography (PPG), an optical technique that measures blood volume variations, dual-wavelength PPG pulse oximeters noninvasively measure/calculate the arterial oxygen saturation (SpO2). An oximeter transmits radiation at a known […]
Magnetometer features field shock recovery
Bosch Sensortec announces its next-generation magnetometer, the BMM350, which provides excellent performance with low current consumption to extend battery life. It enables a wide range of new use cases, including detecting head orientation for 3D audio, and pixel latency reduction in AR/VR to improve the user experience and avoid motion sickness. In indoor navigation, the […]

TDK Corporation announces the availability of the InvenSense T5838 and T5837 MEMS microphones, and the SmartSound One Development Platform. These MEMS microphones push the boundaries of microphone acoustic performance, power efficiency, and advanced feature sets all in small package footprints. SmartSound One offers a solder-free, plug-and-play interface to evaluate and develop multiple types and configurations […]
What is dosimetry? Pt 2
Electronic personal dosimeters (EPDs) provide one of the newest forms of dosimetry. In real time, EPDs provide users feedback on their exposure to radiation. For example, the MBD-2 Tactical/Occupational Personal Dosimeter from Mirion Technologies is a real-time, self-indicating device that operates without user intervention. Intended for field use in military and homeland security applications, the […]
New user-friendly signal conditioner pairs with signal processing system
NewTek Sensor Solutions offers the most advanced and user-friendly signal conditioner that pairs with AC-operated linear and rotary position sensors to deliver reliable feedback in DC voltage, current, and digital outputs for use in factory automation, materials testing, packaging, and dimensional gaging applications. Offering an intuitive set-up of AC-operated LVDTs and RVDTs in process control […]
What is dosimetry? Pt 1
In the broadest sense, dosimetry is done to measure and prevent or at least identify problems from significant or long-term exposure to harmful situations. More specifically, dosimetry refers to the study, measurement, method of measurement or instrument of measurement of radiation dose. Dosimetry often involves wearing a personnel badge, a dosimeter, that measures and monitors […]
What are next generation bio sensing techniques? Pt 2
Part 1 of this blog explored research into localized surface plasmon resonance (LSPR) sensors. This part discusses a surface plasmon resonance/surface-enhanced Raman scattering (SPR/SERS) dual-mode plasmonic biosensor and two other sensing techniques. The SPR/SERS biosensor based on catalytic hairpin assembly (CHA)-induced Au nanoparticle (AuNP) network was proposed for highly sensitive and reliable detection of a […]
