Lecture electronica Conferences > electronica Medical Electronics Conference > Session 4: MOBILE HEALTH MONITORING

14:15-14:45 h | VIRTUAL

Miniaturization is a highly relevant trend in medical and lab technology. Increasing automation, constant object size reduction and increasing accuracy requirements lead to a higher integration degree. Driving applications are lab-on-a-chip, portable units or even invasive components like micropumps or catheters with sensor functions. Conventional photoelectric sensors come to their limits because of size and optical performance data of the components which are used. Rather than sourcing standard mainstream photoelectric elements specialized photoelectric miniature components are designed to fit the applications. Their optical characteristics exceed those of commercially available components. Particularly small precision LEDs, photo diodes, photo transistors and complete laser modules are produced with a special process. Due to the high optical quality, they can also be integrated directly into exceptionally compact device designs. Typical applications are pinpoint sensor functions in medical, laboratory and analytical measurement technology, e.g. Flow monitoring in microfluidic structures, bubble detection in miniaturized pumps, sensor measuring heads, etc. Example 1: Precise detection of liquids Refraction and attenuation of light are the physical effects that can be used in the optical detection of liquids. What is important here is the precise positioning of the transmitter and receiver elements and the optimal selection of the light wavelength, e.g. to use the greatest possible measuring effect when evaluating the optical attenuation of water. The reliable use of light refraction requires particularly precise guidance of the light beam. Example 2: Reliable detection of transparent objects Checking the presence of transparent bodies made of injection molded plastics or glass is often surprisingly difficult. Interfering effects often occur at the interfaces, e.g. Total reflection, scattering or light conduction. The optical detection of transparent surfaces, regardless of whether they are flat or curved, requires a very high quality of the light beam that is precisely tailored to the respective query situation. Application example: magazined substrate carriers. Example 3: Microfluidic channels and capillaries sensing The detection of transparent liquids in microchannels or capillaries is, due to the given dimensions, an optical challenge. The slight differences in the refractive indices of the substances involved make optical detection a special task. Specialized miniature photo sensors are suitable for these applications because of their minimal size and their precision optics. Application example: Lab-on-a-Chip. The light beams from special sensors can be precisely aligned on capillaries or microfluidic structures. By using a special wavelength, for which water has an increased absorption property, a reliable signal is produced even with a minimal channel size. Application example: Detection of micro bubbles in capillary tubes.
