As I worked with small IR sensors since 2016, I produces a controller board to control every Dc or ac motor with every current and I tested electrical board in hand dryer and liquid soap dropper to increase number of products with reduced thermal sensitivity and long lifetime but it was not possible. Since I had to record it as intellectual property right as my patent in the court that it takes so long time since 2020 to now. Also I couldn't find a company to sponsor my products.

If you have similar experience to inform me, I will be so grateful to follow.
