Multispectral light sensor allows low-cost medical imaging

Dr Richard J Curry

A new type of light sensor could support medical and security imaging, and also work with low cost cameras. This is the promise of new research at Surrey University.  The new ‘multispectral’ light sensor detects the full spectrum of light, says the university, from ultra-violet (UV) to visible and near infrared light. One application could be non-invasive medical procedures, such as ...

PCB-based microfluidics for low-cost medical sensing

Themis Prodromakis and Philip King

A fresh look at PCB fabrication could lead to on-the-spot medical tests for disease. Key to the development is the identification, by University of Southampton researchers, that a PCB manufacturing plant has everything needed to make micro-fluidic bio-chemical sensors. Disposable cartridges made like PCBs would clip into a hand-held analyser – also being development at Southampton. The idea is to ...

Protecting the medical devices that protect us

Electronic devices are helping doctors and nurses in healthcare, but even a minor electrostatic discharge could affect the operation of a blood pressure monitor or automated external defibrillator, so designers should factor in circuit protection requirements writes James Colby from Littelfuse. A growing array of electronic devices is available to healthcare providers, patients, and their families, including glucose meters, blood ...

3D sonar fits in blood vessel for medical imaging

US researchers have integrated more than 100 ultrasonic transducers onto a 1.5mm silicon chip. The aim is to create a forward-looking real-time 3D scanner for examining blood vessels from the inside. On-chip signal processing allows the data to be sent down 13 cables, which would form a catheter. Take the Electronics Weekly UK Salary Survey 2014 » “You want the ...

Satellite sensors to be used in medical systems, says Imec

Satellite sensors to be used in medical systems, says Imec

Imec has demonstrated its ultra-compact hyperspectral imaging sensor technology integrated into different commercial camera vendor partners including Dutch firm ADIMEC and SPIE 2014 PRISM awarded finalist BaySpec of the US. Hyperspectral imaging is usually used in high-end remote sensing instruments such as satellites and airborne systems. Imec has demonstrated the technology in lower cost commercial systems. Take the Electronics Weekly ...

Medical panel PC has 21.5in touchscreen

BVM has introduced a 21.5-inch touchscreen panel PC developed for use in medical applications and certified to the third edition of EN 60601 -1. The EN 60601–1 standard defines the basic safety and performance requirements of medical electrical equipment and medical electrical systems used in the diagnosis, treatment, or monitoring of a patient. The fanless unit has an anti-bacterial IP65 ...

Pre-qualified batteries for medical and industrial devices

Staffordshire-based Accutronics has launched a range of pre-qualified Li-ion batteries for medical equipment and industrial electronics. Called VR420, “they are UL-recognised [UL2054], and tested to IEC62133 which is mandatory for medical equipment and becoming important in other markets”, technical marketing manager Neil Oliver told Electronics Weekly. To meet transportation regulations, stored energy is less than 100Wh and the products have ...

Know your MOPPS from your MOOPS in medical power supply design

IEC/EN 60950 is a set of guidelines for the electrical safety of equipment connected to the public power grid, or mains. Now in its 3rd edition, IEC/EN 60601-1 is a further series of technical standards relating to the safety and performance of ‘Medical Electrical Devices’. The regulations are extensive and complicated but two things need to be appreciated when selecting ...

Haswell and its relevance to medical device design

When Intel introduced the 4th Generation of its Core i-Series earlier this year, the standout feature was the quad-core Core i7 4700EQ processor with long-term availability. It is particularly suitable for power-hungry applications in medical technology. Intel launches a new generation of processors every year. While the last processor generation introduced a new low-power 22-nm process technology, the novelty of the recently ...
