Finally, summer is in full swing and the next holiday is just around the corner. I've been daydreaming about kicking back and taking a breather from my everyday office hustle. I mean, who wouldn't want some well-deserved relaxation, right? And you know what else I'm thinking? Getting in a bit more exercise wouldn't hurt either. It's like a double win – feeling refreshed and energized. You know, they say that the best part of any adventure is the anticipation leading up to it. And I couldn't agree more. The thought of that upcoming holiday is already bringing a smile to my face.

However, unfortunately I'm not getting any younger and I'm already dreading the next long drive to my destination. I've been weighing my options, trying to find a better way to get there, but it's proving to be quite the challenge. Trains, for instance, are a popular choice, but they seem to either not be punctual, they do not go to my destination and are simply too inflexible. Flying is definitely not possible, since the CO2 footprint (the guilt is real, my friends) is far too large and there is still a connecting trip by car. In addition, the seats in the plane are also uncomfortable and small, unless you reach deep into your wallet.

Good seats, in affordable cars... Is that too much to ask for? Is the car industry missing the boat again here? I just read an article that stated the following:

24auto: “There are now massage seats in many models. Initially reserved for the luxury class, recliner chairs are now even found in small cars. The relaxation technique is almost the same everywhere: As a rule, individual air cushions in the backrest and seat are pumped up and then the air is released again in order to exert pressure on the back or thighs in specific areas. Depending on how complex the system is, different massage patterns can be implemented: from a wave movement across the entire seat to restriction to individual areas.”

Have you ever wondered how that is done? Well, you’ve come to the right place. Let me show you!

Customized pressure sensors are required for a permanently optimal sitting experience. The sensor measures the status pressure. Air resistance can be increased using a compressor. Ideally, each individual air cushion has its own pressure sensor so that optimal stability is maintained in all areas of the seat.

The car manufacturers buy these tailor-made pressure sensors from Infineon, such as the KP466. This is what the little sensor - called Barometric Air Pressure Sensors (BAP) - looks like:

And here is a sketch of the arrangement of the BAPs for the individual functions:

Incidentally, the Asian car manufacturers are at the forefront here. As already stated by auto24, the range also extends to the mid-range car fleet.

My conclusion

When it comes to picking the perfect set of wheels, there's one aspect that I hold near and dear to my heart – seat comfort. It might sound like a minor detail, but trust me, it's a component that can truly make or break the entire driving experience. So, next time when you want to buy a new vehicle, don’t just be looking at horsepower or fancy gadgets, but rather put those seats under the microscope. The options in the future will be even richer, since companies like Infineon are committed to advancing pressure sensor technology, playing a pivotal role in enhancing seat comfort to elevate your driving experience to new heights.

Have a good ride and enjoy your summer holidays! 🌞
