NYU WIRELESS Prof. Jonathan Viventi and researchers Shih-Cheng Cheng, Yen-Chia Chuan and Jui-Chih Wang have designed a small diameter (25 mm) and low-profile (7 mm) wireless electrophysiology system that can be implanted on different kinds of small animals. The system is designed around commercially available Bluetooth Low Energy components for low cost and ease of use. The size, noise, sampling rate, bandwidth, number of channels, battery life, input voltage range, distortion and cost were some of the challenges faced by the team. The system will be used in a number of freely behaving animal experiments at NYU. The system, including complete circuit diagrams and software, will be made available through NYU WIRELESS.
