What Electronic Components or Sensors can I use in Medical Devices?

Electronic components are crucial in medical devices, enabling accurate detection, diagnosis, and treatment of medical conditions. Selecting precise and reliable components is essential for ensuring optimal performance in medical applications.

Pressure Sensors for Medical Applications

Merit Sensors LP Series in application

Merit Sensor LP Series - Surface mountable pressure sensors

Monitoring and controlling the amount of air, or positive airway pressure, into a patient’s lungs is critical for respiratory support. What you get with the LP Series is a sensor for very low pressures that is easy to solder to a PC board and connect to standard tubing. It is available fully compensated, saving you calibration time and equipment on the assembly line. It is also available uncompensated for lower cost. Once in the application, the LP Series performs with excellent linearity, hysteresis, and stability.

Typical Applications:
  • CPAP
  • Spirometers
  • Ventilators
  • Nebulizers

Medical Level sensing

Coto RedRock TMR (Tunnel Magnetoresistance) sensors are highly sensitive and accurate magnetic sensors, making them ideal for use in medical leveling devices. These sensors excel in precision measurement, detecting minute changes in magnetic fields to provide accurate position or orientation data, which is crucial for diagnostic equipment and patient positioning. Their non-contact measurement capability is advantageous in sterile environments, eliminating contamination risks and ensuring hygienic operation. The compact size of TMR sensors facilitates their integration into small, portable medical devices, allowing for versatile use in various medical settings, from operating rooms to patient bedsides.

Additionally, the low power consumption of TMR sensors makes them suitable for battery-operated medical devices, ensuring long battery life for portable equipment. The stability and reliability of these sensors guarantee consistent performance, which is essential for patient safety and effective medical interventions. Furthermore, TMR sensors can be seamlessly integrated with other electronic systems and software used in medical devices, enabling real-time monitoring and adjustment of levels for optimal equipment performance. These attributes—precision, non-contact capability, compactness, low power usage, stability, reliability, and integration ease—make Coto RedRock TMR sensors perfect for accurate leveling in a wide range of medical applications.

Ingestible and Implantable Devices

Ingestible and implantable devices require efficient and reliable activation methods without compromising their protective encasement. Coto Redrock TMR sensors provide a contactless activation solution, ideal for these devices. For example, capsule endoscopes can remain in standby mode for up to 18 months and are activated when needed without depleting battery life prematurely. These sensors are crucial for ensuring the devices function correctly and maintain their integrity throughout their lifecycle, enhancing patient safety and device reliability.

Hearing Aids

Magnetic sensors in hearing aids facilitate mode switching, diagnostic checks, and response tuning. As demand for smaller, more discreet hearing aids grows, these sensors play a critical role.

Insulin Pumps

Continuous-feed insulin pumps rely on magnetic sensors to detect reservoir status, ensuring seamless insulin management and avoiding complications.
