On 23 and 24 of May 2023, José A. Garcia Souto (UC3M) and Cindy A. Baez Rivera (UC3M) both visited the Silicon Austria Labs GmbH Villach site, in order to perform preliminary testing of the piezoelectric arrays that were kindly sent by Kolja Erbacher (TUB) after packaging of the shielded sensors within the array. José and Cindy brought with them the signal conditioning unit to be used for the array, and 2 days of successful testing were celebrated by a dinner and small tour in the Villach city center.
