Biomedical Sensors in Advancing Medical Field

Table of Contents

A biomedical sensor is basically a tiny device that detects the physical condition of our body by generating mechanical, optical, electrical, and chemical signals. Within this device, there is a transducer that helps to convert one form of energy into another. Biomedical sensors are decisive components of a long list of medical devices and measurement systems.

With the help of this intelligent device, medical professionals can now measure a variety of physical variables, including blood flow rate, pressure, and temperature. Along with this, sensors are also useful in measuring light, electric fields, humidity, velocity, and gas. When it comes to building a range of medical devices, such as respiration pulse oximeters, digital thermometers, location sensors, and digital blood pressure meters, sensors are necessary. Therefore, biomedical sensors have a substantial role in advancing the medical field. 

Types of Sensors:

There are a variety of sensors. Based on four main parameters, such as applications, functions, placements, and types, sensors are generally categorized. If we consider the application area, we will find diagnostics, monitoring, fitness, medical therapeutic, imaging, and wellness sensors. Based on the function, there are different classifications of sensors, such as optical, bio, and mechanical. Electrical, magnetic, thermal, semiconductor, and many more. On the basis of placement, different kinds of sensors are available, including strip sensors, ingestible sensors, wearable sensors, invasive sensors, implantable sensors, and non-invasive sensors. Considering the type, sensors can be grouped into various categories, such as temperature sensors, ECG sensors, blood glucose sensors, blood oxygen sensors, image sensors, motion sensors, inertial sensors, and pressure sensors.

What Are Biomedical Sensors?

Biomedical sensors are used in the medicine and biotechnology field for the detection of chemical, biological, and specific physical procedures of our body. These sensors transmit and report the data so that we can identify the condition of a particular region in our body. Biomedical sensors have a vital role in the lab-on-a-chip devices that helps to exercise the clinical samples.

The application of biomedical sensors in the modern medical field is tremendously expanding, especially when it comes to measuring cerebrospinal fluid pressure, ore body temperature, blood pressure, bone growth velocity, and muscle displacement. While in recent times, many people are seeking home healthcare services, the necessity for medical instruments that involve sensors is rising substantially. The most important part of a biomedical sensor is the miniature coils. The production of these miniature coils is quite challenging because of their tiny size. Manufacturers also need to meet all the tolerance requirements and maintain high standards.

The Role of Biomedical Sensors in Advancing Medical Field:

Biomedical sensors have a crucial role in progressing the medical field. For instance, when it comes to building navigation components for disposal catheters, we require sensors. Biomedical sensors are also essential for performing cardiac ablation through cardiovascular catheters. Let’s take a look at some major applications of biomedical sensors and micro-coils.

  • Sensors has important for various medical treatments, including Radiofrequency treatments, electromagnetic radiation treatments, and heat treatments.
  • Navigation sensors help in conducting in-vivo navigation with the involvement of a local or external magnetic field.
  • Micro-coils are vital components of miniature implants because these coils help to monitor and transfer the data.
  • Micro-coils also provide energy for the electrical charge input or battery charging which is essential for activating and operating different medical systems.
  • Biomedical sensors help to develop plentiful modern medical devices from thermometers to tiny implants.

Biomedical sensors have also created various new possibilities in the production of medical devices. Hopefully, we will have many new medical in recent future that involve sensors.

Production Challenges:

Manufacturers are responsible for maintaining the high quality of biomedical sensors at a realistic price. This is why manufacturers need to focus on mass production. The biggest challenges that a manufacturer experiences during the production of micro-coils are environmental factors and size restraints. To prepare the tiny micro-coils, most manufacturing companies use ultra-fine wires of 9 micron-diameter. While manufacturers wind micro-coils using this tiny thin wire, sometimes they need to join the wires. Joining these ultra-fine wires is very challenging as the traditional methods fail to provide an effective connection. Thermal compression bonding technology is a modern method for connecting tiny ultra-fine wires efficiently. This method is efficient to maintain tight tolerance requirements and high-quality micro-coils.
