he new Recom REM2 series includes modular 2W DC/DC converters with complete medical certification. Thanks to their compact SIP8 package (23.0x8.0x12.2mm) and many variants, they offer developers much freedom in designing their PCB layout. The REM2 series is available from Rutronik UK with many input voltage ranges, all common output voltages as well as single or dual outputs. The board-mount 2W DC/DC converters come with reinforced isolation of 5.2kVDC/1 minute as well as 2MOPP (Means of Patient Protection) at 250VAC at 5.000m. With an input voltage of 3.3 to 24VDC, output voltages between ±3.3 and ±12VDC are feasible. At a bandwidth of 20MHz, the output voltage fluctuates by a maximum of 150mVp-p.
In the operating temperature range of -40°C to +80°C, the modules reach up to 85 per cent efficiency without derating. With a maximum load of 50 per cent they can be used at an operating temperature of up to +95°C. At +25°C the REM2 series has an MTBF (Meantime between Failure) of 12900x103 hours, at +80°C it is 5300x103 hours.
The REM2 series is compliant to class A/B EMC and 60601-1-2 (4th ed.) medical EMC using a simple external LC filter and is certified to CB, IEC/EN and ANSI/AAMI 60601-1 (3rd ed.) medical safety standards. It comes with a warranty of five years.

3D printed medical market grows I
DTechEx reports that the market for 3D printed medical devices and pharmaceuticals will be worth $6.1 billion by the year 2029. IDTechEx finds this to be a rapidly growing market with compound annual growth rates of up to 18 per cent in certain sub-segments. As IDTechEx have previously reported, 3D printing is disrupting the way we provide personalised medicine. IDTechEx described the hearing aid industry as one that has been transformed by 3D printing technology – the digital precision afforded by 3D printing has improved patient comfort while simultaneously decreasing manufacturing times.
3D printing creates invisible braces 3D printing in dentistry is one such high growth market, and one of the most high- profile dental products to be manufactured by 3D printing is the Invisalign transparent orthodontic aligners. These devices are produced by Align
Technology, on 3D Systems’ ProX SLA printers. The Invisalign product is designed to be aesthetically appealing, particularly to adult patients who wish to minimise the appearance of orthodontic appliances. Moreover, as a removable device, the patient has no difficulty with eating, and

of VxWorks Cert Edition. The real-time operating system (RTOS) for safety-critical applications is designed and developed to the highest achievable safety levels accepted by worldwide certification authorities, and now includes a full suite of safety certification evidence across sectors, including automotive, avionics, industrial, and medical. With this latest certification evidence assessed by auditing body TÜV SÜD, the Wind River RTOS for medical is compliant for use in applications requiring up to IEC 62304 - Class C compliance, a standard for “Medical device software – Software life cycle processes.” The commercial off- the-shelf (COTS) software, along with associated evidence package, is designed for safety-critical medical devices, helping manufacturers reduce or even eliminate the validation efforts around “SOUP” (Software of Unknown Provenance). “From surgical robots to smart hospitals, new technology is revolutionising healthcare, bringing new safety and security concerns that must be addressed with stringent industry regulations and standards,” says Amar Parmar, senior director of medical, Wind River.
“Developing secure, safety-compliant medical devices requires a balanced blend of regulatory awareness, proven components, and efficiency of design practices; Wind River addresses each of these factors with the latest release of VxWorks Cert Edition.”
This latest medical certification evidence builds on Wind River’s 20 plus years of experience in safety certification software products, and demonstrates the company’s commitment to helping medical technology developers accelerate time-to- market and reduce costs with next generation software solutions. With its comprehensive software portfolio, Wind River supports a diverse range of medical device manufacturer journeys from design to development to deployment, whether teams require open source and need Linux, or an RTOS, or both. This flexibility allows companies to deliver innovative products that leverage the latest community driven innovations while meeting the safety, security and reliability requirements for mission-critical applications.

New low profile reflective object sensor in PCB assembly
oral hygiene is simplified. Though these devices may not be suitable to treat every patient, they have been used to treat almost six million patients around the world. Many competitors are now seeking to profit from this large and growing market.
3D printing enables affordable prosthetics for growing children An inspiring movement to emerge is the use of 3D printing to create affordable prosthetics for children. Traditional prosthetics can cost between $5,000 and $50,000 and provide an insurmountable financial challenge for parents, as children require a new prosthetic every few months. Charitable organisations such as e- NABLE are using 3D printing to create hands and arms from open source designs to relieve this burden from parents around the world. Not only are the prosthetics affordable, but the lead times are decreased relative to the lengthy customization process of traditional prosthetics. While this application has limited contribution to the overall market value, there are significant unmet needs in the field of prosthetics that are going to be met by 3D printing technology.

T Electronics, provider of engineered electronics for performance critical applications, has announced the versatile OPB9001 PCB module for industrial and medical applications. The OPB9001 includes the OPB9000 reflective sensor and eliminates the need for peripheral circuitry like resistors, regulators and capacitors as such functionality is integrated into its small, robust package. This reflective sensor can detect objects as far away as 50 mm using standard 90 per
cent reflective material as well as objects as small as 2.5mm depending on the object distance. The OPB9001 can also be programmed to recognise various distances within its reflective range.
“Industrial applications often require flexible customized solutions in order to accommodate the dynamic needs of each environment,” says Raymund Chua, product line director, Optoelectronics, TT Electronics. “The OPB9001 product family is capable of directly accepting higher input voltage and can be customised to maximise flexibility and compatibility - even in the most robust and demanding industrial use cases.” All analog signal conditions are incorporated into OPB9001’s integrated OPB9000 IC and PCB assembly. In addition, the OPB9001 is easily mounted on PCBs and panels, and equipped with an integrated connector.
