Designing electronics is tough. Designing electronics that keep people alive is a whole different ballgame. In the consumer world, if a phone glitches, you just restart it. In the world of Medical Devices Development , a glitch can actually hurt someone. The FDA and European regulators are extremely strict for a reason. Yet, every year, we see recalls and redesigns because of fundamental safety oversights. It isn't always because the idea was bad; usually, it’s because the execution missed a tiny, critical detail. Here are the five most common safety failures that engineers see in the lab. 1. Electrical Shock Hazards (Leakage Current) This is the big one. Electronics run on electricity, and the human body conducts electricity very well. If the internal power isn't properly isolated from the patient, you get leakage current. For a healthy person, a tiny shock might be annoying. For a patient with a catheter in their heart, a few microamps can be fatal. Meeting IEC 60...
In healthcare technology, innovation is no longer limited to mechanical design or hardware improvements. Currently, firmware and embedded software are important aspects of the cutting-edge medical devices . Their intelligence can power functionality, precision, and safety. From wearable health trackers to implantable devices, embedded systems can enhance modern medical innovation. The Role of Firmware in Medical Devices Firmware is the specialized software embedded directly into a medical device’s hardware components. It works like the bridge between the device’s electronic circuits and operational features. Firmware controls everything from sensor data collection to wireless communication. In a wearable heart rate monitor, for example, firmware continuously reads signals from sensors, processes the data, and transmits readings in real time accurately. Without firmware, the most advanced sensors and hardware would remain lifeless components. It’s this intricate software la...
