Trước hết, cần chế tạo cảm biến mẫu sử dụng vật liệu nanocomposite trên nền tảng TGS và ống nano cacbon đa vách dạng oxi hóa để đánh giá hiệu quả hoạt động của nó so với các cảm biến sẵn có trên thị trường.
Thứ hai, cần tiếp tục nghiên cứu để giảm hệ số tổn hao của vật liệu trong điều kiện độ ẩm cao. Điều này rất thiết thực đối với khí hậu của Việt nam. Để thực hiện điều này, việc lựa chọn các hạt nano vừa có tính cách điện vừa kỵ nước để bổ sung vào vật liệu có thể là một giải pháp hiệu quả.
