 So here to Brewer Science. So who are you? My name is Ron Trichour. I am the business development manager for our carbon electronic center and what we do here is Brewer Science is a traditionally lithography material supplier but more and more as we evolved over the 30 years. We've been getting into semiconductor equipment. We've been selling temporary bonding materials and now we're also in the business of carbon nanomaterials and as part of this business unit we're right now launching our ultra-fast temperature and humidity sensor. This is a fully printed temperature sensor that can sense humidity and temperature very at a very rapid pace. So real-time? It is real-time so I'm going to do a very short demo so that you can see the response time. So the response time is about 40 milliseconds or less. So I'm going to talk to the sensor and it's going to pick up the humidity from my speech. Testing one two three so you can see it's not detecting a sound but it is detecting my speech the humidity from my speech so you can see I said testing one two three and these signals correspond to the speech pattern. So one of the real applications for this is human detection like security and speech. So in a traditional device it uses voice recognition and then when you talk to a device to use voice recognition I can use a recording and say oh that is me speaking but I might not actually be there but here if I combine a humidity sensor with a voice recognition software you'll get an actual humidity signal from my speech so it tells me that oh that is the real person that's talking and not a recording so that's one application but temperature and humidity sensor can be applied to several devices I mean temperature and humidity sensor on its own is a environmental sensor and it can work with other sensors to give as a compensation because sensors traditionally drift with temperature and humidity and these gives compensation signals. Do different people have different levels of humidity or? Yes it senses humidity between 20% and 80% that's the standard but it can extend to the full relative humidity and it can also measure absolute humidity because it's integrated with the temperature sensor. So what are you showing here on the wall? So here we're highlighting different business units in Brewer Science but traditionally our business has been a semiconductor material supplier for semiconductor manufacturing we have an advanced packaging unit for temporary bonding materials and equipment and we have a semiconductor equipment division our carbon electronics we have a strong presence in LED and energy devices and we supply materials to the MEMS sensors and display market and here it shows a highlight of our carbon electronic center we do materials design materials R&D we have a full-fledged applications lab with several printing equipments and we do engineering services for biomedical companies communication companies and all the all the other customers to do a carbon based printing and parent electronic services and then we also make several devices like the temperature and humidity sensor and these show some of the carbon based devices that we've done and these are and the next poster is our carbon based electronic materials for different printing processes. So what do you think about this conference? I think this has been a really good show for Brewer Science we've had both the material suppliers equipment suppliers and customers that we work with that have been heavy traffic at the boot so I think it's a very good place for us to meet all of our people at once
