In This Issue: Biosensors: Avoiding errors measuring physiological functions like EKG, heart rate, and temperature Wearable medical devices are biosensors attached to the human body to detect and monitor changes and capture biological / physiological data. These devices are usually non-invasive devices that function autonomously. Monitoring older adults and subjects with chronic conditions in the [...]

LoRaWAN

Cost, power, IP, and latency issues are driving IoT designers away from current standards like Zigbee and toward an emerging set of long-range wireless solutions. LoRa, an abbreviation of "Long Range", is one such technology that is gaining traction. LoRaWAN™ (Long Range WAN) is an emerging LPWAN specification developed by the LoRa® Alliance (www.lora-alliance.org). Like all [...]

Biosensors: Avoiding errors measuring physiological functions like EKG, heart rate, and temperature

Wearable medical devices are biosensors attached to the human body to detect and monitor changes and capture biological / physiological data. These devices are usually non-invasive devices that function autonomously. Monitoring older adults and subjects with chronic conditions in the home and community are a growing focus of these applications. Common types of physiological functions [...]

New Regulations for CE: Changing Landscape for Medical Devices in Europe

by Walt Maclay At the 10x Medical Device Conference, which was held in San Diego the first week of May, I learned that major changes have been made in CE requirements for medical devices. After a long delay, the new rules were finally adopted in April of this year. The requirements are becoming more stringent, [...]

Motion Control: Accelerometers, Gyroscopes, and Magnetometers

Accelerometers, gyroscopes and magnetometers all can be used to measure motion. These are packaged similarly to other integrated circuits and may provide either analog or digital outputs. They are widely used in smartphones, gaming devices, cameras, and many other applications. Panasonic, Robert Bosch GmbH, InvenSense, Seiko Epson, Sensonor, STMicroelectronics, Freescale Semiconductor, and Analog Devices are major manufacturers. MEMS [...]

A great way to start the day

No better way to start the day than by receiving a thank you from a client! "I want to thank you for your work on this project. Voler’s approach from quoting the project to completing the work was a rewarding experience, particularly the way risk is built into the proposed budget. I have let others within the [...]

MDT: Testing Error Conditions in Control Software for a Heart Pump

In a recent medical device project, we designed the control software and wrote the verification protocol for a class III heart pump. Our client submitted to the FDA and we are very happy to say that it was approved without any conditions or comments. It was quite unusual that the FDA had no comments on [...]

Ultra Low-Power Design Techniques

If you missed Walt Maclay's talk on "Ultra Low-Power Design Techniques", he shared design techniques to overcome battery limitations often required for IoT, home health, mhealth, and implantable medical and/or wearable devices. It takes a combination of system design, circuit design, and software to achieve an ultra low-power solution. Walt covers the key power saving techniques [...]

Designing Hardware is Hard

We often work with inexperienced teams at startup companies, and we try to advise them about not only the product design work that we do, but the manufacturing as well. The process of transferring designs to manufacturing is not simple, just like the process of designing a product is not simple. There are many things [...]
