Vải thông minh biết chụp ảnhTrong tương lai không xa, loài người sẽ có loại quần áo có khả năng ghi hình mọi thứ trong môi trường xung quanh nhờ một nghiên cứu tại Mỹ.
hip cảm biến ảnh được tạo nên từ vô số tế bào cảm quang (photodiode). Nó có khả năng biến năng lượng ánh sáng chiếu vào tế bào cảm quang thành tín hiệu điện. Hàng triệu tín hiệu điện (có thể được khuyếch đại hoặc không) sẽ được truyền tới bộ phận xử lý ảnh để tổng hợp thành dữ liệu và lưu lên thiết bị lưu trữ. Các nhà khoa học đã thành công trong việc đưa cảm biến ánh sáng vào sợi polymer. Ảnh: BBC.
