Hi there,
Recently, I have designed a new charge amplifier than can be used to implement a precision and low-cost interface for piezoelectric sensors.
I have published an article about the novel proposed circuit in IEEE Sensors Journal. ( A brief information about the new proposed circuit has been included at the end of post)
According to the best of my knowledge, after publication, I have about 1 year to apply for patent.
Now I am looking for a company which interested to buy patentable designs. By searching internet, I found many advice about the methods of submitting new idea to a company. However, unfortunately, I found most of them useless.
Therefore any guidance, suggestion, cooperation offer that can help me are greatly appreciated.
*Any intersted person who wants to collaborate with me can send an email for me through the following email address:

Thank you in advance

[ Brief information about the new circuit ]
The proposed circuit shows it's advantages in the quasi static applications when the low-cutoff frequency of amplifier is smaller than 1Hz. In these applications the conventional charge amplifier usually uses extremely large resistor (in the range of several Giga-Ohm) and electrometer OpAmps. In some application in order to reduce the price of circuit instead of using an extremely large resistor a resistive T-networks is used. However the resistive T-network increases the noise and output dc offset voltage and it's thermal drift significantly.
However the new proposed circuit doesn't need such extremely large resistor at all and instead of using electrometer OpAmp
It can implemented by general JFET OpAmp. The proposed circuit reduce the output DC offset and thermal drift of it (due to thermal drift of input bias current) dramatically without violating noise performance of the circuit. As it has been shown in the article, the proposed circuit surpass the conventional charge amplifier and another patented scheme which was patented by BAE systems (the BAE circuit also uses extremely large resistor like conventional charge amplifier). The proposed charge amplifier has simple structure and it can be implemented by general purpose OpAmp and with
discerete components.
