Patent number: 9454880Abstract: An apparatus for producing an electrosensory sensation to a body member (120). The apparatus comprises one or more conducting electrodes (106), each of which is provided with an insulator (108). When the body member (120) is proximate to the conducting electrode, the insulator prevents flow of direct current from the conducting electrode to the body member. A capacitive coupling over the insulator (108) is formed between the conducting electrode (106) and the body member (120). The conducting electrodes are driven by an electrical input which comprises a low-frequency component (114) in a frequency range between 10 Hz and 500 Hz. The capacitive coupling and electrical input are dimensioned to produce an electrosensory sensation. The apparatus is capable of producing the electrosensory sensation independently of any mechanical vibration of the one or more conducting electrodes (106) or insulators (108).Type: GrantFiled: December 12, 2014Date of Patent: September 27, 2016Assignee: Senseg OYInventors: Ville Makinen, Petro Suvanto, Jukka Linjama

Patent number: 9123258Abstract: An interface apparatus (1600A) comprises a surface (1642) touchable by a finger (120). The surface has a touch-sensitive area with a predetermined position (1646), to which a function is assigned. The finger's presence at the predetermined position (1646) is detected. An electrosensory stimulus is generated to the finger by applying an alternating electrical drive to one or more electrodes (1662). Each electrode is provided with an insulator, which prevents DC flow from the electrode to the finger and a capacitive coupling over the insulator is formed between the electrode (1662) and the finger (120). The capacitive coupling and electrical drive are dimensioned to produce an electrosensory sensation, independently of mechanical vibration of the electrode. The electrosensory stimulus is varied temporally based on the detected presence or absence of the of the finger (120) near the at least one touch-sensitive area having the predetermined position (1646).Type: GrantFiled: May 19, 2009Date of Patent: September 1, 2015Assignee: Senseg Ltd.Inventors: Ville Makinen, Petro Suvanto, Jukka Linjama
