Intellectual Property India Publishes Patent Application for 'Capacitive Sensing System For Human-Robot Coexistence Safety' Filed by Lovely Professional University

MUMBAI, India, Jan. 7 -- Intellectual Property India has published a patent application (202511104194 A) filed by Lovely Professional University, Phagwara, Punjab, on Oct. 29, 2025, for 'capacitive sensing system for human-robot coexistence safety.'

Inventor(s) include Balpreet Singh; Manish Kumar; Dr. Chandra Mohan; and Dr. Suresh Kumar.

The application for the patent was published on Dec. 12, under issue no. 50/2025.

According to the abstract released by the Intellectual Property India: "A capacitive sensing system for human-robot coexistence safety comprising, a plurality of capacitive electrodes 101, a sinusoidal excitation driver circuit 102, a current measurement circuit 103, and a fully integrated on-chip class-D driver coupled with a CMOS analog front end, the plurality of capacitive electrodes 101 detects proximity based on impedance variations, while the sinusoidal excitation driver circuit 102 generates an excitation current with spread spectrum modulation to minimize interference, a current measurement circuit 103 monitors amplitude and phase variations to compute object proximity using Electrical Capacitance Tomography, a CMOS analog front end integrates a high-gain, low-noise amplifier to enhance detection sensitivity, and the class-D driver achieves greater than 85% power efficiency."
